All my babies slept on their back, except for one. One DC had reflux, was colic and didn't sleep. Dc did sleep in a swing, but for safety reasons I didn't let dc sleep there overnight.
Dc did take a pacifier and I put towls UNDER the mattress, to it was on a slight incline.
I also spoke to my pediatrician about this.
Bh this worked and dc was able to sleep at night. This also meant I was no longer a zombie.
Dc slept in an empty crib until he was more active. No blanket or toys.
