Patient Script
For the friend playing the patient role
Character Overview: You are Stuart Hallett, a 34 year old father calling about your daughter Nell, who is 10 months old. You work nights as a baker at a large commercial bakery, from 10pm to 6am, four nights a week, and sleep through the early afternoon. Your partner Marnie, 32, is a teaching assistant on maternity leave. Nell is your first child. You are tired, anxious and a little defensive, because you feel the family should have managed this without a doctor. The health visitor weighed Nell two days ago, said she had dropped from the 50th to the 9th centile, and told you to book in with the GP. You want a plan and a reason. You speak plainly, and you go quiet and a bit choked when you talk about Marnie. Marnie is asleep and did not feel able to join.
Opening Sentence: "Hello, doctor. The health visitor weighed Nell and says she's dropped from the middle of the chart down to the bottom end, and she said to see you. She won't eat her food, she just wants her milk, and honestly we don't know what we're doing wrong."
History if Asked (Data Gathering Phase)
- ●The problem: "Nell is ten months. She was good with food when we started at six months, then over the last two months or so she's gone off it. She turns her head, shuts her mouth, bats the spoon away. She'll take a couple of spoonfuls and that's it. Meals take half an hour or forty minutes and often end in tears. She usually has a bottle about an hour before food."
- ●How much milk: "She has about five bottles in the day, eight ounces each, and one in the night, so six really. She has one before her naps to settle her. And if she won't eat, Marnie gives her a bottle so at least she's had something."
- ●Type of milk and how it is made: "Ordinary first infant milk from the supermarket, bought a tin at a time. We make it exactly as the tin says, one level scoop to each thirty mils of water. We cool it first. We've never added anything or watered it down. She has a few sips of water from a beaker with meals, no juice."
- ●What she eats: "Breakfast is two or three spoons of baby porridge. Lunch is a few spoonfuls of puree or half a finger of toast that she mostly squashes. Tea is a few spoonfuls of mashed vegetables or pasta. No snacks, as Marnie says Nell is too full of milk."
- ●How it started and textures: "At six months she loved carrot and sweet potato puree. We stayed on smooth puree until about nine months. When we moved to lumpy food she gagged, pulled faces and spat it out. She is fine with a banana or toast fingers, but not for long."
- ●Mealtimes: "She's in her high chair in the kitchen. It's usually just Marnie, because I'm asleep at lunchtime and at work at tea time. Marnie puts videos on her phone to keep Nell distracted while she tries to get the spoon in."
- ●Pressure at meals: "I've seen it on my days off. Marnie gets upset and sometimes holds the spoon at Nell's mouth until she opens up. She hates doing it."
- ●Birth and early weights: "Full term, 39 weeks, normal delivery, no problems. She was 3.3 kilos, bang on the middle. Breastfed for about three weeks, then Marnie's milk wouldn't keep up and we moved to formula. She put on weight steadily until about six months."
- ●Development: "She sat up by herself at about seven months, babbles away, waves, picks up things with her finger and thumb. She shuffles on her bottom but isn't crawling yet."
- ●Family history: "No coeliac, no cystic fibrosis, no bowel problems that I know of. I'm five foot eleven and Marnie is five foot five."
Ideas, Concerns, Expectations
Gating note: Stuart does not raise any of the following himself. Each part comes out only when the doctor asks what he thinks is going on, what is worrying him, or what he was hoping for.
- ●Ideas: He thinks she is just a fussy eater, but he also wonders whether something is wrong inside her tummy, because she won't take food. "She's either stubborn or there's something wrong with her insides that we can't see."
- ●Concerns: He fears there is a serious problem. A cousin's little boy needed a feeding tube, and the picture of that has stuck with him. He is also worried about Marnie, who is blaming herself. "My cousin's lad ended up with a tube in his stomach. I keep thinking that. And Marnie's taken it so badly. She says she's failing as a mum."
- ●Expectations: He hoped for tests, perhaps blood tests, to find out if something is wrong, and wants a clear plan. He would take a special high calorie milk if it was offered. "I thought you might do some blood tests. Or give us one of those milks with extra calories in. Mainly I just want someone to tell us what to do."
Associated Symptoms (Red Flags)
Gating note: Stuart answers these only when asked. Every one is negative unless stated.
- ●If asked about vomiting: "She brings up a little bit of milk after a bottle sometimes, a small dribble. It isn't forceful, it's never green or bloody, and it doesn't happen after food."
- ●If asked about stools and wet nappies: "One or two a day, soft and brown, no blood, no change that I've noticed. Five or six wet nappies a day, and they're not dark or smelly."
- ●If asked about diarrhoea, greasy stools or a swollen tummy: "No, her tummy is normal."
- ●If asked about cough, wheeze, breathing, chest infections, fever or urinary symptoms: "None. She's never needed antibiotics or been to hospital. She's well in herself."
- ●If asked about rashes or eczema: "A bit of dry skin on her cheeks sometimes, nothing that needs a cream."
- ●If asked about coughing, choking or noisy swallowing during feeds: "No. She gags on lumps but she doesn't choke or cough on milk."
- ●If asked about tiredness or allergic reactions: "She's lively, up at six and full of beans. No swelling or hives."
Parents and Home Life
- ●Marnie's mood: "She's not herself. She's tearful, she's not sleeping even when Nell is, she's stopped seeing her friends and she says she's useless because she can't get Nell to eat. I'd say it's been getting worse for about two months. She won't say she's depressed. She won't see anyone about it."
- ●Risk to Marnie or Nell: If asked directly about thoughts of self harm or of harming Nell: "No, nothing like that. She'd never say anything like that, and I'd be the first to know. She's just flat out exhausted and low." He is certain Nell is safe with her.
- ●Night feeds and support: "Marnie does the night bottle on her own on my work nights. I do it on the three nights I'm home. I sleep through the morning and the early afternoon, so I'm no use in the day." Marnie's mother lives an hour and a half away and visits most Sundays. Marnie has not told her how bad things are.
- ●Money and food: No money worries and no smokers in the house. "I'm knackered but I'm managing. I'm more worried about her than me."
- ●Availability to be seen: Stuart can bring Nell to the surgery tomorrow afternoon, or on Thursday morning when the health visitor clinic runs at the children's centre.
- ●Declines remote examination: If asked to check Nell on screen: "I don't know what I'm looking for, can't you see her in person?"
Responses to Management (The Negotiation Phase)
- ●If the doctor explains that too much milk may be reducing her appetite and suggests cutting the bottles down:
- ●Reaction: Alarmed. "But she barely eats. If I cut her milk she'll starve." He accepts if told the change is gradual, that she will still get milk, and that food is offered before a bottle. He asks how many bottles she should have. On the night bottle: "Marnie won't cope with Nell screaming in the middle of the night." He accepts a gradual plan.
- ●If the doctor suggests tests or asks about blood tests:
- ●Reaction: Anxious. "Shouldn't she have bloods, to be safe?" If told she looks well, needs a proper check and weight first, and that tests are only done if the examination or the history point to something: "And if she doesn't pick up?" He is reassured that a paediatrician would see her if she did not respond.
- ●If the doctor discusses a high calorie milk, a supplement or a dietitian:
- ●Reaction: Hopeful. "Can't you give us one of those milks with extra calories?" If told that changing how she feeds comes first and that a dietitian can help if she does not gain: "Right. That makes sense, as long as we're not just waiting."
- ●If the doctor asks about Marnie or raises her mood:
- ●Reaction: Quiet, then grateful. "She'll say she's fine." He agrees she should talk to someone. If asked about the health visitor: "She might talk to her. She won't want a fuss." If offered help with night feeds: "I could take a night off." If told Marnie can see her own GP: "I'll pass that on."
- ●If the doctor suggests feeding changes at mealtimes (family meals, no screens, finger foods, not forcing):
- ●Reaction: Receptive but practical. "Marnie's on her own for most of it, and she'll feel I'm saying she's doing it wrong." He agrees to family meals on his days off and will tell Marnie it is not her fault. He asks what to do when Nell refuses: "Do we just take it away?"
- ●If the doctor gives a follow up plan and safety netting:
- ●Reaction: Wants specifics. "How will we know it's working? And what should make us come straight in?" If advice is vague, he asks "Worse how?" He repeats back any specific list clearly and is happy to have her weighed again in about two weeks.

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Stuart is calling about Nell, 10 months old, whose weight has fallen from the 50th to the 9th centile. She drinks six bottles of formula a day and refuses most solids. The station tests whether the candidate can see that this is faltering growth with a probable dietary cause, avoid an unnecessary search for disease, and notice the exhausted mother behind the story.
- ●The model plan has six parts. Take a detailed feeding and mealtime history. Screen for symptoms that would point to an organic cause. Arrange a face to face review to weigh, measure and examine her. Reduce the milk gradually and give responsive feeding advice. Set a weighing and review schedule with referral criteria. Address Marnie's low mood and give specific safety netting.
- ●Acceptable alternatives: seeing Nell and weighing her before any advice, or giving the milk and mealtime advice now and examining within days. Limited targeted tests (urine, coeliac screen because she eats gluten, or iron studies) are reasonable, and so is holding off tests until she has been examined. Early dietitian input, a joint review with the health visitor, or discussion with a paediatrician are all reasonable.
What Counts as Faltering Growth
- ●Faltering growth means a slower rate of weight gain than expected for age and sex. NICE NG75 (Faltering growth: recognition and management of faltering growth in children, checked 6 October 2026) suggests considering the following thresholds for concern: a fall across 2 or more centile spaces if birth weight was between the 9th and 91st centiles, a fall across 3 or more if above the 91st, or a current weight below the 2nd centile.
- ●Nell was born on the 50th centile and has fallen from the 50th to the 9th, which is two centile spaces on the UK WHO chart. That meets the threshold, so she needs a clinical, developmental and social assessment and a detailed feeding history. Using the same chart for every plot, and recording weights in the child health record, is part of good practice.
- ●The most common cause after the early days is inadequate energy intake, and a specific underlying cause is often not found. The history here already explains the fall.
The Feeding History
- ●This is where most of the marks are won. Quantify the milk: how many bottles, how many ounces or millilitres, when they are given, and whether they are given before meals, overnight or after a refused meal. Check that formula is made up as the tin directs, because both over concentrated and diluted feeds cause problems.
- ●Take a solids history. Nell took purees well from 6 months and then went off food over about 2 months, after lumps were introduced at 9 months. She gags on lumps, takes tiny portions and meals last 30 to 40 minutes. This fits a texture and appetite problem made worse by large volumes of milk, rather than an organic swallowing disorder.
- ●Explore the mealtime environment and interaction. NG75 asks clinicians to consider mealtime practices, food avoidance and how carers respond to the child's cues. Nell eats alone with her mother, with phone videos as a distraction, and Marnie sometimes holds the spoon at her mouth. Pressure and distraction feeding are common and understandable, and they usually worsen refusal.
Looking for an Organic Cause
- ●Ask about vomiting and its character, stool pattern and blood, greasy or bulky stools, wet nappies, cough, wheeze or chest infections, fever or urinary symptoms, rash or eczema, coughing or choking on feeds, and energy. Ask about development, birth history and family history of coeliac disease or cystic fibrosis.
- ●Nell has only small non bilious possets, normal stools and nappies, no respiratory or urinary symptoms, normal development and a well, lively presentation. NG75 notes that investigations beyond urinary tract infection and coeliac disease are unlikely to find an underlying disorder in a child who appears well with no other concerns. Reconsider if new symptoms or signs develop.
- ●She has been weaned onto toast and pasta, so gluten is in her diet. A coeliac screen is an option the guideline lists as something to consider if gluten is in the diet, but it is not mandatory in a well infant with a clear explanation and is best decided after examination.
Why the Milk Matters and How to Reduce It
- ●NG75 advises telling parents that drinking too many energy dense drinks, including milk, can reduce a child's appetite for other foods. By 10 months, solids should be an increasingly important part of intake. Nell has six bottles, roughly 1.4 litres a day, which fills her up and leaves little room for food. Offering a bottle after each refused meal reinforces the pattern.
- ●A sensible plan is to reduce gradually over a week or two, usually by dropping the night bottle and the comfort bottle first, giving solids before milk when she is hungry, and spacing the bottles. Milk intake naturally falls as solids increase, but no single volume target is given here, because UK sources vary; the aim is solids offered first and a falling bottle count, not an exact number of millilitres. Formula stays the main drink until 12 months, and cow's milk should not be a main drink before then.
- ●Once her formula falls below about 500 ml a day, check whether she needs a vitamin D supplement, as the NHS advises that babies having more than 500 ml of formula a day do not.
Mealtime and Food Advice
- ●NG75 recommends encouraging relaxed and enjoyable mealtimes, eating together as a family, letting children feed themselves and be messy, keeping meals neither too short nor too long, setting reasonable boundaries without punishment, avoiding coercive feeding, and establishing regular schedules such as 3 meals and 2 snacks.
- ●Practical points for Nell: stop phone distraction, give finger foods and soft lumpy textures progressively, and offer small portions of energy and iron rich foods first. If she refuses, the food can be taken away calmly without a bottle straight afterwards. Stuart can join meals on his days off.
- ●Short term fortification with energy dense ordinary foods and a referral to a paediatric dietitian are options where more energy is needed. An oral nutritional supplement or a special high energy formula is for continuing faltering growth despite other measures, so it is not first line at this visit. Tube feeding is a specialist decision and is not relevant here.
Monitoring, Referral and Safeguarding
- ●Agree a management plan with specific goals. NG75 suggests weighing usually no more often than fortnightly between 6 and 12 months, because more frequent weighing can cause unnecessary anxiety. Weigh on the same scales, plot and record in the child health record. Length should be measured no more than every 3 months. A fortnightly review with the health visitor is a sensible route.
- ●Discuss with or refer to a paediatric specialist service if there are symptoms or signs of an underlying disorder, failure to respond to primary care measures, slow linear growth, rapid weight loss or severe undernutrition, or features that raise safeguarding concerns. Do not admit unless she is acutely unwell or has a specific need.
- ●Here there is no safeguarding concern: the parents are caring, seek help, and the baby is well. Say so, and say what would change that view.
Marnie's Mood and the Wider Family
- ●NG75 recognises that maternal postnatal depression or anxiety is associated with faltering growth, and CKS lists family stress as a risk factor. Marnie is tearful, exhausted, withdrawn, feels she is failing, and does night feeds alone. This may be postnatal depression or anxiety, and it matters both for her and for Nell.
- ●The candidate cannot assess Marnie through her partner, but should ask about risk, suggest she is seen by her own GP or the health visitor (an EPDS or similar assessment), and offer practical help, such as Stuart sharing night feeds. A reasonable alternative is to ask the health visitor to contact Marnie, or to offer an appointment for Marnie in her own right.
- ●Recognise the emotional impact on parents, and avoid blame. Explain that feeding difficulties are common and the plan is shared.
Common Mistakes in This Station
- ●Ordering a wide screen of tests, or referring urgently, for a well infant with an obvious dietary explanation.
- ●Giving a fortified milk or supplement before trying milk reduction and feeding advice.
- ●Advising an abrupt stop to bottles, or switching to cow's milk as a main drink.
- ●Making a plan from the video without arranging weighing and examination.
- ●Missing the mother's low mood, or labelling the family as neglectful.
- ●Asking for daily weighing, or giving no review date or referral criteria.
- ●Vague safety netting such as "come back if worse".
