Is diarrhea normal in a baby aged 1-3 months?
Applies to age: 1–3 months
In short
Diarrhea and vomiting are common in babies too and usually stop after a few days. For persistent vomiting, especially with blood, call 999 (the ambulance number in Poland) or 112 (the emergency number in Poland); if you are worried about a baby under 12 months, an urgent medical assessment is needed.
