Every single time I put my 5 month old on his playmat he immediately flips its right over his face and stays like that struggling to take it off then I'll come back in the room because he sounds muffled and I'll take it off his face so what does he do when I leave the room, put the playmat right over his face again. What should I do? I don't want to take it away from him because it's his favorite toy out of the millions of gadgets and gizmos we have for him examples his exersaucer, jumparoo, walker, sit up chair, swing etc... anyway he's always so contenta and extra happy on his playmat he can stay on it for a good hour unlike everything else. So I'm at a loss it doesn't seem like it's pressing against his face and the sides stick out opened but he seems to struggle and it just doesn't seem safe I tried putting something heavy on the playmat to keep it down but that just bothers him.
