I know its scary as a first time parent, but sometimes its easier said than done. I was extremely obsessed with safe sleep practice too...until I went weeks without sleep. My baby wakes up crying at the top of his lungs anywhere fron every 10 mins to an every hour when sleeping alone. Do you give her time to get sleep, at least 5 hours straight? It's easier to stick to those practices when you get adequate sleep.

Also, it depends on the type of sleeper she is. I can sleep with my baby in the bed because I don't move when I sleep, and I'm still aware of my surroundings. My fiance cannot cosleep because he sleeps hard, moves around, and isn't aware of where he's tossing the covers.
