I'm not sure I had a favorite childhood toy. We had a lot of toys but it was mostly your classic toys like wooden blocks, tinker toys, and random baby dolls. We ocasionally got something like a My Little Pony or a new Barbie but I wouldn't say that any one of them was my favorite.
I had the doll my mom made me for Christmas when I was 5 up until last year when I decided that I had to let her go. She was in really bad condition and was taking up closet space.
