content: I really wish I had not wasted my money on these things. We bought them to put in the tub for our baby who has just transitioned out of an infant tub. I cleaned the tub well, let it dry, then wiped the surface with alcohol, and let it dry again. (Just as a side note, our tub is completely smooth and not textured.)I put these down and on the first use of the tub 2 of them came off. Ever since then they have been peeling up one at a time. SO annoying and unsafe for my little one. If I could return these pieces of crap and get my money back I would. If they actually stuck like they are supposed to, they would be great. During the first use of them they really kept my baby from sliding around in the tub. Now that so many of them have come up she slides around and gets upset. If I didn't need the ones that are still hanging on to stick until I can get more, I would have ripped them up a week ago. Don't waste your money.
