We used the snuggle nest for maybe 3-4 weeks after DS was born. He would wiggle his way down the little slope so, it just didn't really work out for us. Also, we have a queen size bed so, IMO not enough room for me, S/O, and the snuggle nest.
There's no weight limit. We transitioned DS from our bed to the crib using it. (And have used since since when he was sick and we preferred to co-sleep.) We even used it without the positioner when he no longer fit in it. Eventually I took it away (naps first, then overnight) because he was swaddled and wiggling all the way out of it and to the bottom of his crib.

Also, she's in this in her crib. Not in our bed.
