Molly

I keep seeing all of these things on recommended lists and I just feel like we shouldn't need all of them? But which are the essentials? Im trying to figure out what we need for a newborn of the following list, experienced moms, please help!

Bassinet

Rock n play

Pack n play

Bouncer

Swing

(I'll definitely get a crib for later)
