hi!I havent had a chance to read the above posts so sorry if there similar,i had to FF my DD after breast feeding and i was told to get the closer to nature tommee tippee bottles,there were dearer but were great,she didnt take well to other bottles i really struggled untill i got those although they were dearer i think because there real close to a nipple shape,and depending on age they have 1 2 or 3 for slow to meduium flow.I just had from new born i think 2 of the smaller sized ones then i bought another 4 i think saves re washing them all the time.I just got a cheaper version microwave steraliser was quick and easy to use.and a bottle brush.I didnt have a bottle warmer,i used to use the babys rooms if out or take a flask etc.one of those formula dispensers are a life saver too!
