This product is very cute and serves a necessary purpose to protect the eyes.  My little guy is 6 months and knows that he can pull them down very easy, so they don't usually stay put for very long.  I'm hoping that he will get used to them and let them stay where they are supposed to.  The only flaw I see at this time is when they are put on they seem to line up just above his ears and make his ears flap out (not cute).  I'm just hope he will grow into them eventually.
