N, 8 months old, loves to knock the magnets off of the fridge and try to put them back on. It never even occurred to me to let her experiment with these until she tried it at a friend's house. Now it is my "go to" activity for when I'm trying to cook dinner. If you haven't done this yet with your little one, give it a try. Be careful with the cheaper magnets (shown above) because the little piece of magnet sometimes falls off of the back.
