I use the Breastflow- The first years bottles.
They mimic a breast. Probably shouldn't start using them till 4-6 weeks though unless you're planning on not breastfeeding. However, I gave my DD the breast, a bottle, and a paci. It's just not recommended due to nipple confusion.
I got a breastpump from WIC.
Diaper bag- diapers, wipes, couple onesies, pacifier (if you plan on using one), socks, mittens, hat, umm...
