My Lo pooed as I gave birth to him and it was a huge load of muconium, he obviously didn't need to go again for awhile as he didn't do another poo of muconium for 2 whole days after he was born, then after that he didn't poo again for 5 days, mw said it was nothing to worry about as it just meant he needed every ounce of my milk and there was no waste, when he did his next poo it was the bright green stuff and there was a lot, since then he poos at least twice a day. I wouldn't worry while he is still so new as his system is just settling down and probably using up every drop of milk, but be warned when he does go boy those first few are humdingers lol!!!
