hi leah, i dont want to be a pain or anything, but i had to comment because of the other posts you got... please please do not put him to sleep with any pillows or bumpers or on his tummy,,, they all put him at risk for sids. sorry, its the facts. i know lots of people do it and everything was fine, my parents did it, as did their whole generation. however, sids is down around 40% since the back to sleep campaign. thats a big percentage. its not worth it. as for the flat spot, get him out of the bouncy/swing/ whatever more often if you can, just put him on the floor whenever you can. once he moves around more, it will probably even out. and in the crib i would recommend maybe hanging a mobile or putting one of those music lights things attached to the side of the crib to draw his attention to that side. if this doesnt work, you might want to be sure the doc checks his neck,, i had 2 friends who had babies with a short ligament or something in their neck which made it physically difficult to turn to one side. both very easily corrected with a short duration of physical therapy. and if he does end up with the helmet, its really not a big deal. a couple of my friends had it, it seems like it will be awful at first, but its not. its pretty cute, and its just a short while, and my friend was actually more relaxed because she wasnt always worried when he would fall all the time when he was learning to walk! either way it will be ok, just please keep him safe in the crib.
