Reddit reviews Similac Slow Flow Ready to Use Disposable Nipples and Rings Set of 50

When you go on your hospital tour (or any time before birth) ask your nurses what brand of formula they supply in the hospital. Hopefully you can use theirs the whole time but just in case you have to use yours I think it's a good idea to bring the same kind, just so you're not switching it up on baby so early (you can always change it later at home under the watch of your ped if you want). If you get the 2oz RTF like Similac, for example just know that there's usually 1 or 2 nipples for every 8 bottles. If you don't want to wash and reuse in the hospital (which I wouldn't recommend) then you'll want to bring extra disposable newborn nipples, too.

ETA - you might actually want to set up a chat with the lactation consultant for immediately postpartum. Get a feel for their agenda beforehand - if it seems like they're super militant then maybe try a different avenue, but if they seem to respect your choice to formula feed then they should actually be able to walk you through how to safely balance expressing colostrum/milk (so you don't end up engorged) with stopping production. I tried pumping every 2/3 hours for a month but never made any real amount of milk and was able to just stop cold turkey with zero evidence that I'd ever tried in the first place, but many women who actually DO produce milk will have to go slowly to "dry themselves up" - else they risk infection.
