I found almost everything useless except a good collection of carriers that I expanded on over the months (started with a soft Moby wrap, added an Ergo, a mei tai, a woven wrap, more buckles, good baby carriers are so awesome!) Oh, and breasts. Cloth diapers.
Things we DID NOT use:
Baby bathtub. Babies like to be on mother's chest where temperature is naturally regulated and heartbeat is soothing and milk is flowing. Best bedtime ritual ever. Mama and baby in a lavender oil bath.
Baby socks. Impossible! Useless! Great as finger puppets in the middle of the night when completely insane and sleep deprived and trying to wake spouse.
Crib. Great for torturing yourself with trying to get baby to sleep in it. Great for holding clean clothes.
Bassinet. See Crib.
Baby nail clippers. Impossible to use on baby fingers! Easier to just bite off nails with my teeth honestly.
Breast pump. Didn't listen to The Womanly Art. Gave myself oversupply. Major, major suckage. (har har) WOrried constantly about how much was pumping for no reason.
Stroller. He hated it. Wanted to be on mama's chest. Baby carriers trumped fancy expensive stroller, sold it after a year and three uses.
Bibs. They catch nothing. You're still going to wash that shirt.
Diaper bag. Any nice comfy large bag will do; leather totes wipe easily, canvas is very washable. After a few months I didn't really see the point in toting all that stuff with me anyway, left it in the car.
Things I will get this time:
EXTRA SHEETS FOR MY BED. Plus those nice reusable waterproof pads (Amazon has them, great for homebirths) so when the breasts and the mama and the baby all leak at 2am, no big deal.
MORE CARRIERS. Because, really, can you ever have too many? A woven wrap for the newborn this time instead of a stretchy. Plus what I still have from my 3 year old.
Baby hammock. Making my own.
Wool covers. Bulletproof.
Baby shirts. Onesies are ridiculous.
Bidet. Because every birthing mother deserves one!
