FTM here due in June. I'm trying to wrap my head around this world of parenting that I know nothing about, but let's just start with bottles... I have every intention of breastfeeding, but if my experience is anything like most mothers I've personally known, there will be plenty of pumping in my future.... I know there are ump-teen bottle brands out there so how do you go about navigating through it all? What do you look for? What kinds of differences are there? I'm looking for the "what", but also the "why".
