My baby was born at 37 weeks 4 days at 6lbs 5 oz. she started off pooping fine. She got jaindice and a bit sleeping and started losing. She got down to about 5 lbs 10 oz. she then started eating great. We went to lactation and after eating they would put her on the scale and she always got enough milk. She is gaining weight just fine. Looks good acts content but she will skip a day or two pooping and then have a huge diaper. She is 2.5 weeks old and hasn't pooped in almost 5 days. The doctor is not worried at all because of the good weight gain and because she was born a bit early so it can take a bit longer to get going, but everything I read says a newborn should poop 4 times a day at least at this age. Any ideas?
