Hi, DS is 5 1/2 months old, slept in sleepyhead every night since we brought him home. Lately he's started rolling over and sleeping on his side which is fine for naps or when he's cuddled with me, but I'm not sure if I should let him sleep like this for the night. He's still right next to me so I can see and hear him, I'm just worried he might roll on to his front or squish his face into the bottom and not get back up. Might be over thinking it because he's completely sound asleep just now, but if I roll him back on to his back he will wake up within a few mins and thrash around until he's on his side again.
