My tall fluffy butt girl is having a hard time fitting into pajamas! We mostly have been using Carter's footed sleepers plus some Little Me and a few random ones. She's just moved completely out of 9 month sizes (and is about to outgrow 6-12 month) and the Carter's 12 month cotton PJs are super tight on her midsection (although 12 month fleece fits well but it is becoming too warm for it). Baby Gap 6-12 month has fit well but it seems she's about to outgrow that in length. I think some of the problem is the snug fitting rule for 12 month + sizes. Help! What brands of PJs fit your fluffy bottom babies???
