I know how you feel. My 4 1/2 yr old boy lives on carbs. Will not eat anything else. Would rather starve than try something new. Loves pasta, rice, PB and J, and only processed meats. I thought as he grew older I could reason with him, hasn't happend yet.

On the other hand my 8 year old girl goes in spurts. I try one low carb meal a day, sometimes two. Usually breakfast and dinner. For lunch I let her fend for herself. Sometimes she sticks with it and tells me she took the bread off the burger,other times doesn't. She is a very athletic kid, plays soccer and softball, she didn't need to loose weight, but she did. 11 lbs! Little things like that add up.

Good luck with your kids!
