Safe to fall asleep in?

My baby is a week old and during the day we let her sleep in this. It’s the graco pack n play. At night she sleeps with us in our room in a bassinet. I guess I’m confused bc now just reading in my what to expect when you’re expecting book the first year. It says if they fall asleep in something like this take them out immediately bc of sids. But this was meant to sleep in. Do they just mean all night? Or even if I am watching her in this she she’s taking a nap it’s ok? I’m a new mom and worry about sids 24/7. :(
