I would be LIVID if someone did that to my child. Sorry but thats almost abusive. Its like dr's who try and make children crawl by maneuvering their legs roughly to get them "used to it". Every child develops differently and it doesn't mean there is a developmental issue. I once read about a competitive swimmer who said that as a baby she commando crawled yet people say that its a developmental issue, and infers that the child won't have very good co-ordination in later life... well that sure debunked that theory hey? I would make a complaint. Maybe if they spent more time interacting with her she might feel like actually moving around.
