Amazingly my mother kept many of the toys I had as an infant. Even more amazing, 40 years later my niece is playing with them and they work (I also learned that Sesame Street is still on, but sadly most of the actors are dead). In fact her favorite toys are my old Sesamee Street playschool sets and we play with them for hours.
Now I have an 18 month old who can say my name, but every time she sees sees me she calls me Ernie.
