This is my second post today! I'm turning into a right little MN-er!
My son is 16 weeks old and is fed half and half with formula and breast milk. I feed him at 7am and at 2pm and he has formula for 11am, 6pm (well, technically thats half expressed breast milk and half formula mixed up in a bottle) and 11pm feeds.
So, he really is on half and half and his poos are now a bit weird............ When I was exclusively BF-ing him (up until 8-9 weeks), he had started to go longer between poos i.e. about 3 days. This has continued but, recently, its extended to 4 days between poos and we even got to day 6 last week! Anyway, I wouldnt worry about it as he is happy and smiley etc etc and certainly doesnt appear to be in any way constipated. However, he has started to cry/yelp when he poos and he certainly strains to get them out now. I find it upsetting that he looks upset by the process and am wondering if they are hurting him or if its pretty normal for babies to start to get a little more involved in the pooing thing rather than them just slipping out (lovely!)
Also, BTW, they are a real mix of dark green (yuck like ducks poo really is that normal?!) which is quite thick and the bright yellow of breast milk poos which are still a little more watery. I think the colour is because the yellow mixes in with whatever colour formula poo would be (!?) but there is also a very clear differentiation between the two poo types! Never the twain shall meet really! Weird!
Anyway any thoughts welcomed as Im just a little concerned that I should, in fact, be more worried about the long gap between poos and possibly even that colour......
Green poo is often a sign of a tummy upset - normally just a run of the mill virus. Nothing to worry about. However if he is regularly straining, ask the GP for some lactulose to soften the stools, some kids just take a while to get used to pooping I guess - DS did - but after a few months on lactulose he grew out of the problem
