Buying my toddler boy clothes for fall/winter and debating on size. He just turned 2 and is in the 90+ percentile for weight and height. He weighs 32 lb now. I bought 3T and its big on him now. Mostly casual pants/tees for daycare. Ideally they would last through late March/early April when it starts to warm here. Would you stick with 3T or exchange for 2T? Do they grow quickly at this point? What's your experience?
