can a girl child way this

Hi I'm trying to order these for my 3 year old nephew who wears a size 8T ... what size in little kids would fit him?

My nephew is a size 12 toddler, which size would that be? I’m a little confused about that, it says 12 little kid?

will these fit a toddler with wide width feet?
