I don't recall one either. But I was a young child in the late 1950s. I do have a teddy bar and a doll from my childhood, but they're in a box in a closet.
I was glad to grow up and excape my overcontrolling mother who infantalized me.
Gee, I might need a sippy cup, though, if I keep on--and an adult bib. I'm now bad about dropping my foods and drinks on myself.
