Query: fun - but not safe

My eight month old son really enjoys playing with this toy. This morning, he grasped the top of it and pulled himself up to stand. He was so proud of himself, smiling at me -- then, the whole thing toppled forward and his little face went smashing into the floor. Now I need to figure out how to return and buy a toy that ISN'T going to knock out his brand new teeth.
