Yes, she did.
And I have a 5 year old cousin and they wear the same size clothing. It's crazy because she's super active AND a picky eater. She has been keeping a steady weight and not gaining though. Pedi says she's fine
Yeah she's just going to be "solid". She may even slim down as she gets older and more active. You can't sweat weight too much at that age unless she was just a ball of pudge waddling around double fisting oreos.
