My daughter is 12 weeks old (6 weeks corrected). She is exclusively breastfed and she hasn't done a poo for 3 days. I know that's perfectly normal but she is obviously uncomfortable with it. She has really foul smelling wind and now she is bloated and her stomach is firm. I've tried massage, cycling her legs, a warm bath and eating more fruit to her help along but nothing's happening. I can feel rumbling in her tummy when I massage it. What can I do to help her? And should I get her checked because of the bloating and firmness?
