Are they getting enough exercise? I know you said they go to dance, but if it's only one or even two classes per week that is much exercise really.

This came to mind only because there is a girl in one of my daughters' dance classes that is overweight. Her mom says she doesn't understand why, after all she takes a dance class...

My kids' classes are 45 minutes and they aren't fully active the whole time, so this 45 minutes once a week isn't much exercise at all. They need that amount or more per day.

Just a suggestion, that even if you feel like they are getting enough exercise, they might need more. Something where they are running, climbing, skipping, hopping

I also agree with having their thyroids checked. Does obesity run in the family?
