My DS (almost 5 months) discovered how to roll over onto his tummy yesterday. He can't roll back over and hasn't figured out that he can put his head to one side. I have just discovered him asleep on his belly, face down into the mattress, not crying but struggling a little to lift his head up. I turned him over and he didn't even wake up.
Now I'm worried and can't sleep in case he does it in the middle if the night and I don't notice. What can I do? I've googled and found things I could buy, but that's no good tonight, I've seen something about towels but am worried about putting towels in the cot because from past experience he's likely to burrow into then.
Anyone have any advice?
