- Allergic reaction to proteins in cow's milk and cow's milk products, causing inflammation of the digestive tract.
- Occurs in over 1 in 25 babies.

✅ What to do
Gentle, practical steps you can take at home — start at the top.
- If breastfeeding, eliminate all cow's milk products from the mother's diet.
- If the infant is eating other foods, exclude cow's milk entirely.
- If the symptoms disappear once cow's milk is removed, the diagnosis is confirmed.
- Switch to goat's milk — the curds are smaller and goat's milk is generally easier to digest.
- Soymilk may be a partial solution, but ensure the child is getting adequate vitamins, minerals, and calcium.
- When cow's milk is removed and the cause is addressed, the child recovers quickly and resumes gaining weight.
