DS hasn't pooped in 2 days. He doesn't seem to be in any pain (yet), but I'm starting to get nervous. He's had a couple diet changes this past week and a half- going from being supplemented with RTF formula to a diet of nearly all powdered formula. It's the perfect recipe for constipation! I'm just not sure what to do. And of course it's a Sunday and the dr's office is closed haha. Isn't that how it always works!
