Does or has anyone done this? Someone suggested we try it with H because he really doesn't like lying on his back or flat. We're trying it tonight for the first time. We haven't got a wedge, which was what was suggested we use so we used books instead but it seemed a little high and H ended up turning completely the other way round. So my OH took the books out and is using a flattened pillow. So far it seems to be working. I put H in it half awake and normally I would have to stroke his hair to get him to go fully asleep but I left him and he fell asleep himself. I'm just a little worried about using a pillow, it is under the top end of the mattress though. Has anyone else done this? .
