Paediatric allergy · London
Milk ladder reintroduction programme - London.
A structured iMAP milk ladder for children with cow's milk protein allergy - a named consultant paediatric allergist, a specialist paediatric allergy dietitian, and a written home plan with clear stop rules and weekly check-ins.
Why parents choose us
- 01
A paediatric allergist and dietitian together
Not a one-off appointment. A named consultant paediatric allergist works with a specialist paediatric allergy dietitian across the whole programme.
- 02
The right ladder for your child
The iMAP ladder is the framework. We tailor step timing, portion sizes and stop rules to your child, their symptoms and their history.
- 03
Independent, and free
We are paid by no clinic, so the recommendation is impartial and costs you nothing. You choose the consultant that fits your family.
Indicative pricing

What it is
A structured way back to milk, one small step at a time.
The iMAP - International Milk Allergy in Primary Care - ladder is a stepwise reintroduction of cow's milk protein for children with IgE or non-IgE cow's milk protein allergy. It starts with small amounts of heavily baked milk and progresses over months to unbaked cheese, yoghurt and finally fresh pasteurised milk.
-
Is baked milk safe first?
Baking denatures the milk proteins that most children with mild allergy react to. Around 70% of children with mild IgE allergy already tolerate well-baked milk.
-
Why not just try fresh milk?
A sudden challenge with fresh milk risks a larger reaction and is harder to interpret. Small, predictable steps let you and your allergist read your child's response.
-
How long does it take?
A typical ladder takes around 6 months, roughly 4 weeks per step. Some children move faster, others need a pause. Slower is safer than rushed.
The pathway
From first enquiry to fresh milk - what happens, in order.
One team from first message to the top of the ladder - allergist, dietitian and a named point of contact for the weekly check-ins.

Who benefits
The children a home milk ladder is designed for - and the ones it is not.
iMAP is designed for children with confirmed cow's milk protein allergy, aged from around 6 to 12 months upwards, whose eczema and gut symptoms have settled and who have had no recent severe reaction.
-
Non-IgE cow's milk protein allergy
Reflux, colic, blood or mucus in stools, or eczema flares that settled on a strict cow's milk exclusion under a paediatrician.
-
Mild IgE-mediated cow's milk allergy
Historical mild hives or vomiting on cow's milk, with reassuring recent skin prick and specific IgE results.
-
Aged from 6 to 12 months and older
iMAP is designed for infants and toddlers ready to eat baked wheat, from around 6 to 12 months upwards.
-
Resolving eczema on a milk-free diet
Eczema that is well controlled, so a flare during the ladder is easier to interpret and less distressing.
-
Growing and thriving on substitution
Adequate calcium, vitamin D and energy intake from a specialist formula or fortified plant milk, confirmed by the dietitian.
-
Ready to move off specialist formula
Families who want to move off extensively hydrolysed or amino acid formula onto everyday dairy in the family diet.
-
Recent severe reaction - not suitable at home
A history of anaphylaxis, wheeze or a large IgE-mediated reaction means a supervised oral food challenge first, not a home ladder.
-
Red flag: FPIES or acute wheeze on milk
Repeated profuse vomiting an hour or two after milk (FPIES), or wheeze on milk exposure, needs specialist review before any reintroduction.
The six steps
What each step of the iMAP ladder actually looks like.
Six steps, roughly 4 weeks each, with dietitian check-ins between. Higher-risk children start Step 1 in clinic as a supervised oral food challenge rather than at home.
-
Step 1 - Malted milk biscuit or cracker
Roughly 1.6 mL of cow's milk protein baked at high heat. A small piece to start, building up over 3 to 4 weeks at home if tolerated.
-
Step 2 - Milk muffin or scone
Around 3.2 mL of milk protein, still heavily baked. Homemade recipes are shared so you know exactly how much milk is in each portion.
-
Step 3 - Pancake or waffle
About 4.8 mL of milk protein, cooked at a lower temperature. This is where many children with non-IgE allergy stall, and the dietitian revisits the plan.
-
Step 4 - Hard cheese
A small amount of unheated cheddar or similar hard cheese. Fresh cheese introduces less-modified milk protein for the first time.
-
Step 5 - Yoghurt and soft cheese
Plain yoghurt, cream cheese and butter. Portions built up gradually with dietitian review of gut symptoms and skin.
-
Step 6 - Pasteurised fresh cow's milk
Full introduction of fresh cow's milk in the diet. Once tolerated, dairy comes off the exclusion list and into the everyday family diet.
-
Home vs supervised
iMAP is designed to be a home ladder for non-IgE and mild IgE cases. Anything higher risk should be started in clinic as a supervised oral food challenge.
-
Second-opinion review
A specialist review of a paused or failed ladder from elsewhere - sometimes the fix is a step change, sometimes a formal challenge, sometimes more time.
Where in London
A small London panel of paediatric allergists, we picked them.
Consultant paediatric allergists at The Portland Hospital, HCA The Wellington, GOSH International Private, and Chelsea and Westminster Paediatric Private. Introductions are made privately once we understand your child's case.
Selection criteria
How we choose every paediatric allergist in our London network.
-
Consultant paediatric allergists with experience of the iMAP ladder
-
Specialist paediatric allergy dietitians for calcium, vitamin D and growth
-
On-site skin prick, specific IgE and supervised oral food challenge pathways
-
Clear escalation to a paediatric allergy MDT if the ladder fails or symptoms change
Success rate
Around 60–80% of children with IgE-mediated cow's milk allergy outgrow it by age 3 to 5 years, and rates are higher again in non-IgE mediated allergy. The ladder helps identify tolerance earlier and gets children back to dairy safely.
Safety at home
The rules that keep a home ladder safe.
The milk ladder is a well-established programme. The things worth planning are when to start each step, what to do if a reaction happens, and how to keep calcium and vitamin D on track while you climb.
-
Start at home only when your child is well
Never start or step up on a day with fever, viral illness, an eczema flare or a wheeze. Wait until baseline is settled before the next portion.
-
How to manage a reaction at home
Stop the ladder, give the antihistamine the allergist has prescribed, and take a photo of any rash. Call 999 for breathing difficulty, floppiness or repeated vomiting.
-
When to use an adrenaline auto-injector
If your child has been given an adrenaline auto-injector, the allergist trains you and any nursery or school on when and how to use it before you start.
-
Roughly 4 weeks per step
Give each step around 4 weeks of regular exposure before moving on. Slower is fine. A rushed ladder is the commonest reason for a false failure.
-
Non-IgE symptoms can be delayed
Colic, reflux, loose or mucousy stools and eczema flares may take hours or days to appear. Keep a simple diary during each step so patterns are easy to see.
-
Keep calcium and vitamin D on track
While climbing, most children still need a specialist formula, fortified plant milk or supplements. The dietitian reviews intake at every stage.
-
Soya, lactose and lactose intolerance
The milk ladder is for milk protein allergy, not lactose intolerance - a different condition. Soya cross-reactivity is uncommon and reviewed case by case.
-
Nursery, grandparents and food labels
Everyone who feeds your child should know which step you are on and what they can and cannot offer. We share a one-page plan you can send on.
-
Red flags that stop the ladder
Any wheeze, swelling of the lips or face, drowsiness, repeated vomiting or a large hives reaction means pause the ladder and speak to the allergist that day.
Reading your ladder plan
Your ladder plan in four parts. Read the last one first.
Whichever consultant you see, the plan you take home keeps to the same shape - so nursery, grandparents and both parents can read it at a glance.
A quiet reminder
Allergy language can read coldly - we translate it for you.
If you would like us to talk you through the plan before your first step, just ask.
- 01 Header
Your child, the diagnosis and the goal
Age, weight and growth, IgE or non-IgE picture, recent skin prick and blood test results, and the goal - baked milk, dairy, or full fresh milk.
- 02 Plan
Which step you are on and portion sizes
The step, the recipe and portion size, how often to give it, and how long to stay on this step before considering the next one.
- 03 Findings
Reactions, symptoms and diary notes
Any hives, gut symptoms, eczema flares or breathing changes since the last review, and how they were managed at home.

Recognised by major UK insurers
Cover for paediatric allergy consultations, testing and supervised food challenges is usually funded when medically indicated. Dietitian cover varies. We confirm before booking.
Frequently asked
Everything parents ask about the milk ladder.
Quick answers on home safety, reactions, insurance, the dietitian, soya and lactose, and repeating a failed ladder.
-
Is the milk ladder safe to do at home?
The iMAP ladder is designed for children with non-IgE cow's milk allergy or mild IgE-mediated allergy to do at home, once a paediatric allergist has agreed the plan and the family has clear stop rules. Children with a history of anaphylaxis, wheeze on milk, or FPIES should have a supervised oral food challenge in clinic first, not a home ladder.
-
What do we do if our child has a reaction?
Stop the ladder that day and give the antihistamine your allergist has prescribed. For a mild rash, take a photo and send it in the weekly check-in. For any wheeze, swelling of the lips or face, drowsiness or repeated vomiting, treat as an emergency - use the adrenaline auto-injector if one has been prescribed and call 999. Return to the last step your child tolerated, and speak to the allergist before starting again.
-
Does UK private health insurance cover the milk ladder?
Cover varies. Most UK insurers fund the paediatric allergist consultations, skin prick and specific IgE tests, and supervised oral food challenges when medically indicated. Dietitian sessions and the wider structured programme are sometimes only partly covered. We check the exact policy wording with your insurer before you book.
-
Do we really need a dietitian?
Yes, in almost every case. A paediatric allergy dietitian checks calcium, vitamin D, iron and energy intake while your child is still avoiding milk, times the ladder around growth and weaning, and gives you age-appropriate recipes with known milk-protein content. Without a dietitian, families tend to under-fortify the diet and stall on the ladder for no clinical reason.
-
What about soya, lactose and lactose intolerance?
The milk ladder is for cow's milk protein allergy, not lactose intolerance - lactose is a sugar, not a protein, and is a different problem. Some infants with non-IgE milk allergy also react to soya protein, so the allergist reviews this at the start. Lactose in baked milk portions is not usually a problem unless there is a separate lactose intolerance.
-
Our child failed the ladder before - can we repeat it?
Often, yes. Many children who stall or react on one step tolerate it again after 6 to 12 months of continued exclusion, so the ladder is repeated from a safe earlier step. A specialist review looks at what happened, whether recent skin prick or specific IgE results have improved, and whether a supervised oral food challenge is a better next step than another home attempt.
