Second + children...

[TJR2119]

Well, I learned from both children. So if we ever have more I know we don't need: a crib, a swing, so many clothes and toys , more than 1-2 bottles since we nurse exclusively, etc.

Really all I think we would need would be:
Clothes, pacis, a bumbo, exersaucer, 2(ish ) baby carriers, car seat, and diapers. Maybe 1-2 bottles for daddy to feed baby and a manual breast pump since I pumped maybe 2x for dh to feed dd, and receiving blankets since my babies like being swaddled.

Maybe a bassinet/ playpen combo. DD liked to sleep in the bassinet part sometimes. And when she was bigger, her and ds liked to play in the playpen.

The essential for us consist of:

Gear:
Graco Carseat (we use this as our "bouncy seat" too)
Good quality stroller
Bag (can be any big handbag to store essentials when out and about)
Fisher price cradle swing
Fisher price Jumperoo (entertains baby and we also use this when we are outside and baby can't walk yet. No need to be holding him all the time.)
Tiny Love play mats

Carters onesies Llots and lots. We don't use bibs just change baby's onesie)
Soft cotton pants
Sleepers
Socks
A few hats
A few warm outfits

Feeding:
Medela manual breast pump
One Soothie pacifier (the hospital one)
Two bottles for when out and about
Avent Sterilizer (We also use it to sterilize other kiddie items such as sippys, we don't use a dishwasher wich can serve the same purpose)

Diapering:
Two dozen GMD prefolds and 8 covers, baby wipes, 2 snappis
A&D Ointment

And probably a few other things I forgot to mention. But we've never used a playpen, bouncy seat, electronic toys for baby which is what you were asking lol!
