It seems to be mostly when he's either having a tantrum of sorts, or while play time. It's almost like he doesn't even see it. Or he thinks he can just run through it. He has an eye appointment in May because my other two children wear glasses so it's his first appointment just to check if there are any issues.  But I don't think there are any issues per say because one time he tried running through the wall three seconds later he found a pacifier wedged under his crib ?? Go figure.
