Hi
My baby is 16 weeks old, nearly 4 months and for the last two weeks she has started being sick (thick gloopy running out her mouth) after majority of feedings (breastfed) it usually occurs immediately after when you sit her up or sometimes an hour after. She has never really been sick before this why has itnonly started at 4 months. Should I be concerned? She doesn’t have a fever and is putting on weight.
