Discovered by accident that DS3, who's three months old, can settle himself to sleep from awake - but only if he's lying on his side - basically in the same position he feeds in. He also has a strong preference for lying on his right side rather than his left.
I found this out because he's just getting over a nasty cold and he really struggled to sleep on his back, even when the head of his cot was elevated on books and we had a pillow under his mattress. I propped him on his side against a rolled up towel, with a smaller towel against his tummy so he couldn't roll onto his front.
He's on the mend now, but is now refusing to sleep on his back. When on his side he sleeps through (by which I mean he wakes to feed a couple of times per night but otherwise sleeps).
Would IBU to keep lying him on his side? I figure that in a couple of months he'll be rolling and capable of holding himself in his preferred position without towels, so what's the harm in keeping going. But am I missing any obvious flaw in my plan?
I've read on (American) websites that as long as he's not on his front or at risk of smothering (on a towel, which he isn't, because the towel in front of him only goes up to his tummy) then he's not at increased SIDS risk.
