My 5 year old is a size 2 😩 but he’s also 4ft tall and 60lbs sooo he’s a big kid. All of my others were about a 11/12 at 5! So I’d say it’s pretty normal!
That's about the size my kiddo wore at that age. She's in a women's size 6 now. She's a tall kid.
My 4 year old is almost in a 10 . By winter his boots will be a 10. I'm pretty sure it's normal. My 10 year old is in a 3.5 almost 4. Lol
