Query: Dangerous!!

This was given to my son as a Christmas gift. Its really very unsafe. It is top heavy, and has fallen on my son more than once. When he tries to pull himself up to a standing position, the whole thing slides towards him because it isn't heavy enough to support him. Then he slides underneath it and it falls down on top of him! And that is WITH THE WHEELS LOCKED. If I unlock the wheels it becomes even more dangerous. I'm getting rid of it.He liked the lights and noises it makes, but there are so many other options for this kind of toy that I would NOT buy this one!
