Baby allergen tracker
Getting peanut and egg in early is the easy part. Keeping them, and seven other allergens, in the baby's week for months is where most families slip: the trials that prevented allergy fed peanut regularly for years. Tick each serving here and the tracker shows what is due again this week.

How it works
Log each serving with its date. An allergen that has been started but not given in the last 7 days shows as due again: Australia's allergy society (ASCIA) advises offering each one at least once a week once it is in the diet, because stopping may let the allergy develop.
Peanut and egg are counted in grams of protein. In the LEAP trial, babies at high risk ate at least 6 g of peanut protein a week, and the US guideline (NIAID, 2017) aims for 6 to 7 g over three or more feeds, about 2 g each time: 2 teaspoons of thinned smooth peanut butter, 21 softened peanut puffs, or 2 teaspoons of peanut powder. In the EAT trial, eating at least 2 g a week of peanut or egg-white protein went with fewer of those allergies. A whole well-cooked egg counts 3.6 g of egg-white protein, so just over half an egg a week reaches 2 g.
The other seven are counted as servings, since the trials did not show a clear weekly amount for them. Most guidelines say to start allergens around 6 months, never before 4 months, one new one at a time, when the baby is well.
General information, not medical advice. If your baby has severe eczema or has already reacted to a food, talk to your doctor or an allergist before the first peanut or egg. Swelling of the lips, face or tongue, widespread hives, vomiting, coughing, wheeze, trouble breathing, pale or blue skin or sudden floppiness need emergency help at once.
