I thought it would be perfect for Toots since he is turning two in less than 2 months. I didn't pay much attention to the sizing but just looking at it I knew it would fit him so I put it in the cart and kept going. It wasn't until I got home and was putting things away that I caught the tag. It's a size 12 months. Yes, my soon to be 2yr old is wearing a shirt made for a 1yr old. Anybody want to bet his pediatrician tries to send us to some sort of therapy after our next well check?
