How much tummy time do you guys do with your babies? My little guy is 15 weeks old. He has very good head support, likes to sit up (supported), and absolutely loves using his legs (literally drags himself everywhere on his back using his legs or jumps around in his exersaucer), but he has absolutely no arm strength - or doesn’t know how to use them. So when he rolls on his tummy, he’s stuck there and I worry about suffocation. Any tips ??
