Hey Mona we must be on the same wave length. I just posted this question a couple of days ago
.Most of the suggestions were for Hanna Anderson which apparently is a bit on the $$ side. Other than that I think suggestions were for sweats and babyGap and Old Navy. Someone said that some wahms make pants specifically for cd bums but no links and I haven't done a search on that yet. Also one poster said that she bought toddler-size capris for her dd so they'd fit in the bum but not be too long. HTH
Old Navy and Gap seem to be the best for us, I fit Joe into a 3-6 month gap pair on Sunday (he is almost 11 months and in a 24 month/2t for everything else) so they are cut bigger. Check out e-bay to get them cheaper, and osh kosh overalls have big bums on them too!
