I bought these blocks for my 11 month old son for Christmas. I gave them to him to play with the next morning. After about 1 minute (literally), he was able to pull off one of the stickers on the blocks whole and eat it. I was able to retreive some of it from his mouth. He swallowed the rest. I called Fisher Price and put in a complaint. I am not thrilled with the idea that the stickers came off that quickly and have returned this item.
