Do you remember when your LO outgrew the RNP for sleep (not just hanging out in during the day)? What about a bassinet?

DD2 (8 weeks) currently sleeps well in the RnP. She's in our room and will be until she's ready to share with big sister. We will move at some point in the coming months, too (and then they won't share) so I'm trying to think ahead if we can get by with what we have or if we need another solution before moving.
