It took me a long time to figure out what size to buy for my son's first birthday as only 1 and 2 year olds are available. After reading the reviews I bought the 2 year size and it fits perfectly! He has just switched to 18 month old clothes and they are a bit too big for him. I don't usually review, but I wanted to contribute to this one. Everything should work out on her 1st birthday!
