My DD is 9 weeks old and normally eats around 5oz each time she has a bottle, not sure how much when she is on the breast but I express and formula feed often.
Anyway she hasn't done a poo for 3 days and is only eating 2oz every 3 or 4 hours and only having one 6oz bottle a day and that's it. She will have a breastfeed and seems happier with that as don't think a lot comes out each time, a few ounces probably.
Anyway I was wondering is it OK for her to not eat this much? Is it because she needs to poo, because she is straining/wanting to poo but isn't able to poo yet (second day of straining, usually does it every 2 days).
Is this OK or does it need to be taken up with the doctor?
