C is 2 different sizes, she generally fits 24m in weight but is 2T for length. (27lbs2oz and 34.25")

Obviously, we've been buying 24m/2T (Carters fits in 24m and is sometimes too long!) She lives in jeggings but the waist is too big and I have to cinch in adjustable waist pants to like the 5th button. Shirts is not too much of an issue. 24m shirts fit fine.

It's really, really annoying.

Anyone else have this issue? What do you do? What are the best brands for pants?
