Who invented these?

I have decided that people with out kids designed the little bike I have for Alexis. It has a great theory though, child sits on seat and puts feet up on pegs and parent pushes them with a handle. Ok now you are all probably wondering what is wrong with that…all the steering control is in the child's hands. It was a great walk for her though, she didn't scream because she wanted to walk. I didn't' go the full distance either. It was torture the whole way around the block. She would turn the handles in the direction she looked and so I had to keep it from jolting sideways. I will be looking for a new bike at garage sales in the next few weeks. Ok well I need to go and make dinner.
