My daughter is in the 30th percentile and is still comfortably in 9-12 month clothes at 14 months. I'm trying to figure out what size to buy her summer clothes but I don't know how much she'll grow and if she'll fit into 12-18 or 18-24 months by the summer. She'll be 18 months in May, I can't see her outgrowing the 12-18 month stuff we have as she's still too small to fit into them, but I don't know what size to expect her to be by August. How much did your little ones here between 1 and 2?
