All good tips. Mine is if you don’t live alone. I did nights with 6 kids and a husband. I never who would be home at any point in day. I got a good lock for our bedroom door. When I hunker down for a sleep I don’t have to worry that someone left the door unlocked and I’m gonna get robbed in my sleep My house might get robbed but i guess I feel safer sleeping with my area secured.
Plus kids who could see the sign on door saying moms sleeping and still tried…no luck. Lol

Ours is a keypad so my husband could always get in room if necessary

Also with phone. I put it on do not disturb. But because I have kids I had it so the school and my husband could get through. No other calls though

For me getting my brain to shut down helped. So knowing if kids school needed me I could be reached. My kids knew to hit dad up first with calls too

Good luck
