Fisher Price

Has anyone had a problem with Fisher Price Laugh and Learn Chair?
My daughter has had her 2 weeks and have established themselves 5 + times, I called Fisher Price today, they will send me a label to replace it, and then they will send me a check to replace it with something else, she climbs on the seat and then the arm, … I can not see her every second, so it is now stored in the closet.
Ours works fine. Perhaps this is an operator problem?
