I found the cutest most neat Mommy and Me aprons with large front pouch and matching bear faces.
Both are green in color and have ties at the neck and waist. The waist tie is quite long and should fit most adults. The length of the neck tie can be changed to fit depending on size.
Both have a pocket on the front which means your kiddie can put his utensils in there just like Mum.
I like that having a cartoon face it really appeals to the younger kids and makes for a bit of adult/child fun in the kitchen. No doubt though your child may want to wear it everywhere, not just in the kitchen.
