Hi Dr , My baby is 27 days old. I used to feed her by expressing with pump and feeding her with spoon because she is not breastfeeding properly I'm trying that too but she won't suck properly.But now when I feed her with spoon she cries too much and since past 4 days she is vomiting frequently and that too with high quantity and because of that she is not sleeping properly..I don't know what to do please suggest . Also is bottle feeding safe for 27 days old baby?
