Baby food allergy tracker for starting solids & BLW

AllerLog is an iPhone app for tracking a baby's first foods. You log meals and ingredients, rate how your baby liked them, and add a 1–5 sleep and poop score. AllerLog then charts every ingredient so the foods that line up with bad days stand out.

It's the habit of waiting a few days after a brand-new food before adding the next one, so a reaction is easy to pin on a single food. The CDC and the American Academy of Pediatrics suggest one new single-ingredient food every 3 to 5 days. It matters most for common allergens like egg, peanut and dairy. Ask your pediatrician what pace suits your baby.

Immediate reactions such as hives, swelling or vomiting usually start within minutes and up to about 2 hours after eating. Delayed reactions, like some cow's milk allergy symptoms, can take hours to days and often show up in poop, skin or sleep. Repeated vomiting 1 to 4 hours after a food can be FPIES and needs a doctor.

It can. Tummy discomfort from gas, constipation or a food that doesn't agree often shows up first as restless nights, though teething, illness and sleep regressions are more common causes. If bad nights keep following the same food, that pattern is worth tracking and sharing with your pediatrician.

There's no single look. Signs that a food may not agree include runny or very frequent stools, mucus, unusually hard or painful poops, or a sore, red bottom that keeps coming back after the same food. Blood in the poop always needs a call to your doctor.

Use a checklist of the major allergens with the date of every serving and anything you noticed afterwards. In AllerLog, flagged allergens sit under their own filter and each serving schedules a check-in an hour later, so the record builds itself as you log meals.

Yes. AllerLog is free to download, and the core tracker is free too: meal logging, sleep and poop scores, ingredient charts, allergen flags, check-in reminders and history. An optional Premium subscription adds Insights (possible intolerances, a watch list, new this week) and AI Insights.

No. AllerLog is a tracking and journaling tool that helps you and your pediatrician spot patterns. It doesn't diagnose allergies or intolerances and isn't a substitute for medical advice. If your child shows signs of a severe reaction, call emergency services.
