but he has a cold and as he's co-sleeping with us we can't just raise the mattress, so for the last 10 nights or so he's been sleeping on the wedge I used to tuck undder my bump when I was pregnant. Add to that all the time he's spent in the car seat, whether because he couldn't be laid flat even while he was awake, or because of my having to ddo errands.
Am I condemning him to a lifetime of expensive osteopathy? Does anyone know what happens to a baby who isn't laid flat to sleep, or is it all specualtion?
