Can anyone tell me if you have found little girl clothes that run long? My dd is very long but seriously has the skinniest little belly! She eats like a hoss, and has adorable little chubby legs and cheeks but she has this little washboard stomach (I wish I could get my stomach to look like hers!!). She is too long for most 9-12 month pants for length but the waist on the 9-12 is enormous and the 12-18 literally slide right down. I have been buying 12-18 month leggings since they are a bit more snug but she kinda looks a little goofy with a HUGE gap in the waistband of her pants! Any suggestions would be appreciated!
