I received this set as a gift and it's labeled for 6 mos+ so we started playingwith them when he was 6 mos. These are really dangerous - my son puts theanimal head in his mouth and because it's rubber-like material, it SEALS aroundhis mouth and he CANNOT BREATHE. This happened with the penguin and the hippo.I put them away for a month and let him try again at 7 months, but same story.This is REALLY SCARY as he could not remove the animal himself because it suctioned on him(and he's too young to know how to remove it).PLEASE do not buy this toy. I have never written an Amazon review but felt obligatedto share this story. I have never written a product complaint, either, but willtry to find the appropriate government organization so that I can file a complaintrequesting this product is no longer sold. Please do be careful.
