Safe Sleeping Best Practices?

Sh
Looking for advice from experienced moms. FTM here with a baby on the way this summer. I'm curious how closely other moms follow the safe sleeping guidelines. From what I've read, babies should... 
1) Only sleep on flat surfaces and only on their backs. 
2) Have no blankets, pillows or stuffed animals in their sleep space at all. 
3) Share a room with us for the first 6 mos to a year. 
I see baby's asleep with blankets and stuffed animals on here all the time. I also see babies sleeping in their Rock N Plays; so I'm just curious if you think these guidelines are overkill or if you follow them to a T?
Thanks! 🤰🏾👶🏾💤
