Re: Infrequent bowel movements + green stools
Relax! In a baby who is otherwise happy, healthy, and growing, green poop is not a big deal and not a health problem. My second child had poop that was almost always green- anywhere from fluorescent green to dark spinach green- for months and months, and was perfectly healthy. I mentioned the green poops to my pediatrician, and she was never concerned about them.
I would only be concerned about green poop if the baby was not growing well, or if the poops contained significant amounts of blood in addition to being green. So I'd probably skip the appointment with the gastroenterologist. In all likelihood, the gastro. will just shrug, and possibly suggest that you eliminate dairy or some other likely useless step.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
