Query: Beware of this toy

Although my 10 month old son loved this toy, he was able to pull it over on top of himself, which caused a major bump on the head. It is not sturdy and any child who is learning to stand or is uses it for balance will either fall on it or pull it over on top of themselves. We're putting it back into the box and bringing it back to the nearest toys "r" us. There are plenty of other toys out there that are just as entertaining and much less dangerous.
