Apologies for the subject heading :)
Posting here for traffic. My DS is 5 weeks tomorrow and hasn't pooed in about 36 hours. He's EBF, feeding well (I express into a bottle 2 to 3 times a day so know he's having at least 120 ml at each feed - usually more as he snacks on the breast afterwards) and everytime I change his nappy he's done a wee, but no poo.
He seems to strain and exert quite a lot. If I was to guess I'd say he was getting tummy cramps as he doesn't bring any wind up when it happens but after a few minutes they pass and he settles down. I don't think he's constipated as he went for a while without doing a poo last week and when he finally went it was a normal colour / consistency. They seem to be worse first thing in the morning, starting around 4am - he wakes up but doesn't feed, just strains, which makes me think he'd actually sleep through a good chunk of the evening if they weren't waking him up.
Otherwise he seems happy out.
Anyone else had this? Anything I can do to help him along?
