Diarrhoea in infant

My girl had similar after every feed for about a week when she caught a viral thing, so three days is still early lah. Since she's got the runny nose and cough too, it's likely all connected, but I'd bring her to see the PD just to be safe especially since she's an infant, just to rule out anything that needs attention. Keep her well hydrated in the meantime and watch her nappy output and energy levels. Hope she feels better soon.

If she is otherwise feeding well and having plenty of wet diapers, it may just be a viral infection, which can cause diarrhea along with a runny nose and cough. Keep her hydrated with frequent breastfeeds or formula, and keep an eye on her wet diapers. Since it’s already been 3 days, I’d check in with her pediatrician, especially if the stools are very watery or she seems less active.
