Don't know how much this formula forum gets seen these days, but worth a try... So with #1 in hospital, even though the midwives insisted that he was latching well and feeding well, I knew he wasn't. The first night with him was literal hell, he tried to feed constantly and screamed pretty much the whole time, very unhappy baby and exhausted post-section mumma. The hospital midwives were not in the slightest bit helpful. However, on our second day my own midwife came in to see me and baby, and right away she suggested mixed feeding: expressed milk bottles alongside formula. And she gave him some of the hospital's bottles which were pre-made SMA ones*. The difference was amazing, he was a happy and content little lad after that. Anyway this time I plan to try breastfeeding again but plan ahead and take in formula just in case. And I didn't realise until very recently, but apparently you can buy the premade bottles, ready sterilised. I figure that's a lot less faff than trying to clean and prep bottles when I'm post-section and can barely move, I could just keep a box of them by the bed. Thing is, I can't find anything online about how long they keep for. I know the pre-made cartons have a long shelf life, but no clue about these bottles. I'm 22 weeks now and starting to get the bags packed just in case, but don't know if I should order these formula bottles now or leave it as long as possible...? Has anyone used them, do they keep for a good long while? Don't want to be making baby poorly with old formula milk!! *SMA® Pro First Infant Milk From Birth 6 X 70ml Starter Pack - Boots << these are the ones I mean.
