I don't know about boys, but for girls there are a few pants out there with Lycra (esp. at the Children's Place). . .they look like regular pants, but that bit of stretch makes it perfect for CDs. And, of course, you can't beat leggings from anywhere! I do tend to use just CPFs and a Bummis pull on for going out, though, so it's a trim combo anyway.
I had these for Zeke and I ordered some for Alek because they are by far the biggest in the butt I could find out there and giving that my sons have thunder thighs it really helps us out!
How did that happen, this was suppose to go under one of the questions someone asked about diapering pants. UGH! I need glasses.........no wait I have glasses! I need a cup of coffee!!! ARGHHHHHHHHHHHHHHH
