The milk ladder takes months.
This remembers it for you.

Well Tolerated is a simple app for parents working through the milk ladder with their allergist — the steps, the recipes, what you gave, and what happened after. All in one place, on your phone.

What it does

Four things, done properly

Every step, with the recipe

The ladder starts with milk baked into a biscuit and ends with a glass of milk. Each step shows the food, the recipe, and how much milk a portion actually contains — so you are not guessing in the kitchen at seven in the morning.

A log that takes ten seconds

Date, how much, what time of day, and whether anything happened afterwards. If something did, you pick the symptoms from a list instead of trying to describe them from memory three weeks later.

The whole history, in order

Every feed and every reaction, from the first biscuit onwards. Filter it down to just the reactions when you need to see a pattern.

One page for the appointment

Months of feeding condensed into a single summary you can show your allergist or print and take with you. No scrolling through a notes app in the waiting room.

What is the milk ladder?

Many babies who react to cow's milk protein grow out of it. The milk ladder is the usual way of finding out, and of getting dairy back into the diet once they have.

It works because heat changes milk protein. A biscuit baked at 180°C for fifteen minutes contains milk the body is far less likely to react to than the same milk in a yoghurt. So the ladder starts with the most heavily baked form, in a tiny amount, and works up through muffin, pancake, cheese and yoghurt to plain milk — one step at a time, several days on each, moving up only when the step before went well.

It is slow on purpose. Some reactions take two or three days to appear, which is why each step needs at least three clear days before it means anything. Done properly it takes months, and the hardest part is simply keeping track.

That's the part this app is for.

Before you start

Who it's for

This is for you if

  • Your child has a delayed (non-IgE) cow's milk allergy
  • Your healthcare provider has told you to start the ladder at home
  • You want one place for the recipes, the record and the dates

This is not for you if

  • Your child has an immediate (IgE) milk allergy
  • There has ever been a severe or whole-body reaction
  • You haven't spoken to an allergist about reintroducing dairy yet

A ladder for immediate allergy belongs in a clinic, under supervision — not at your kitchen table. The app asks about this at the start and will say so.

Being straight with you

What this is, and isn't

Well Tolerated keeps your record. It shows you the published ladder, the recipes that go with it, and everything you have logged. That's the job.

It does not replace your allergist. It doesn't diagnose anything, it doesn't decide whether a symptom was a reaction, and it doesn't tell you when to move up a step or go back one. Those decisions stay with you and your healthcare provider — the app just makes sure you walk in with the full picture.

If something worries you, stop and call your healthcare provider. If your child has trouble breathing, swelling of the face or lips, or goes pale and floppy, call emergency services.
