LO is almost 7 weeks old, and she's been sleeping in the newborn napper attachment on the Pack N Play for a few weeks now (since we stopped co-sleeping).
I'm wondering when to transition her to the regular Pack N Play mattress (at 'bassinet' height), and whether anyone has experience with this.
Was it a big change for your LO, going from tightly held to wide open spaces? She's swaddled every night, but I don't know how much of a difference it will make. Any thoughts?
