Sleeping on stomach

A few days after my last post.. my former 24 weeker was discharged from the hospital. 💕

We have been home for almost a week now, and he only likes to sleep on his belly/contact nap. We are living for the contact naps during the day, but nights have been really hard getting him to sleep in his bassinet. I have barely slept the last few nights trying to get him settled because he only likes sleeping on his stomach.

Any advice? We obviously want to practice safe sleep but this is a unique situation. What helped your baby’s learn to sleep on their backs?
