Unfortunately I think at least part of the answer might lie in nutrition. We do try to eat fairly well at home: I buy almost nothing but whole wheat bread (yes...the real stuff), lots of fruits and veggies, etc. But the kid LOVES carbs and milk. He showed a real sensitivity to milk as a baby and was on part soy part milk for a long time. This kind of stuff is just so hard to figure out because there are so many pieces to the picture.
Anyway, done venting, but if you have any ideas...please let me know.
On a very happy note: I think we are just about potty trained (OK OK, potty learned....for those of you that are on that whole parenting thing...). He's been doing SO good and tonight didn't want to take his underwear off to swap for a diaper...wahoo! There's still an issue with #2 I think...so we're not quite 100%, but he's been doing great and has trained himself very quickly. I know he's over three, but I had hear HORROR stories about pushing things with boys before they were ready...so we just waited until he wanted to. So happy we did...I hope it sticks with all this other stuff going on now.
