I had trouble choosing the size for my son's first birthday as there are only sizes for 1 and 2 years. 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!
