DS is 13 months old and in the 90% for height and weight. He fits into 24 month carter's onesies with room to grow. I'm expecting him to be in 2T by fall. I want to pick up some stuff on clearance, but I worry when fall comes it won't fit and I'll be out the $$. He grew super fast when he was little, and seems to have slowed a tad now. He is just now outgrowing his footie PJs from last fall (they were big then).
Once your LO hit the 1 year mark, how quickly did they move up in sizes? Think I'll be safe buying 2T for next fall/winter? Is there a huge difference between 2T and 3T, specifically with length of pants?
