Also helps for baby to sleep on their side (using bolsters to keep them there - we use men's tube socks filled FIRMLY with white rice and then the ends
knotted - they're heavy enough to keep a small baby
from rolling over and also work as hot / cold packs via microwaving or freezing)- just like sleeping on their left side helps some with indigestion / heart burn during pregnancy (letting gravity pull stuff
in / toward the
stomach organ and anything trying to go back up has to get past the gravity pull).
