I have a 2 week old who after passing all the meconium, has had the normal mustard colored poop, but it's foamy. We do EC so we see it coming out, and it's really a lot of bubbles. And it's more liquidy than I remember from my first child. He seems fine. But he was a big child at birth. 9lbs 7 oz. And he is now only 8 lbs 14oz. He's only gained 2 oz in the last 5 days. My first child was gaining a lot faster. So needless to say, I'm a bit worried. I have spoken to my doctor who said to keep an eye on it. So has anyone else experienced foamy poops with their newborn?
