Re: What the heck?
maybe he's just done?
for spitups, try putting a brick at the head of your bed to elevate it a couple inches.
you can also, at least once he's a bit older, pull him into a sitting up/forward postion and rest him against/across your belly at 90 degrees. my 11 month old has been sleeping like that for months. i'm not sure how well it would work/how safe it would be with a 9 day old - you may have to experiment.
