BF and pooping

apeyg

My LO is almost 4 weeks old and is EBF. He has never really pooped a whole lot(he has never pooped after every feeding like my DD did) I mentioned this at his 2 week appt and our pedi said as long as he is eating well and having wet diapers that he wasn't too worried about it. Well now he has gone over 2 days without pooping. He last pooped on Wednesday evening. Before that he hadn't pooped since Monday. On Wednesday his poop was the normal BF baby poop (yellow, seedy, ect.) He is eating fine and acting fine. He has a lot of gas but he always does. Of course now it's Saturday so I ?can't call the pedi. When should I start to worry?? Anyone else have this experience? TIA
