Help!!! Bottle sets & nipple flow

Aubrie • Mommy & wife 👶👪💍

Hi mamas, I'm currently 21 weeks pregnant and I'm finishing up my registry. I need major help finding and picking out a low priced bottle set for my son when he gets here. I'm honestly not comfortable breastfeeding, while I know its best for baby. I have no idea what sizes of bottles to get or anything at all about nipples. Can someone help?
