I've been trying to figure out what the name of an old show I used to watch is. It's a children's television show from the late 80s or early 90s (I think). It was about a family consisting of a mom, dad, and son. The dad was a scientist. The story line was that the family wanted a little girl so the dad built one. The little girl was always trying to fit in. I remember that she always had a red bow in her hair.

Hmmm sounds like one I use to watch. The little girl's name was Vicki and she walked and talked like a robot. The show was called Small Wonder.

Could this maybe be the one you are thinking of?
