TikTok ? apologies, I know that my emotions are colouring my argument. Yes, ?arsenic? was a wild exaggeration, sorry.
Re the BFing literature: ok, again, I?ve been letting my emotions get in the way of things. However, I have an NHS BFing magazine here, and to quote ?Compared with a full breastfed baby, a baby who is artificially fed is: 5 times more likely to be hospitalised with vomiting and diarrhoea; 5 times more likely to suffer from urine infections...? etc. Over the page, it states (in bold and capital letters!), ?...artificially fed babies are disadvantaged in health terms compared with breastfed babies and have a greater tendency towards developing many other illnesses in later life?.
It?s maybe all true, but you said this type of wording was rare, but here it is. While not hinting at arsenic, of course mothers (or at least me, but I can?t be the only one) are left feeling that they are endangering their child. Which is what ?midwife? was implying with her Ed and car seat objections.
By wider context, I meant ? I take it that all these studies of BFing and risks etc eliminate all other influencing factors e.g. socio-economic factors which have a massive impact on our health/life expectancy, genetic dispositions, geography, environmental factors etc? Or, for example, is it the case that mothers who BF or BF for longer are more likely to be in higher socio-economic groups, have better access to healthcare etc? There are other factors that influences our health.
Re the John Lewis thread ? yes, I do think some of the undertones were that an area wasn?t needed because, to quote ?We live in an FF culture?.
Truthsweet ? if being shown how to make up bottles etc is supposed to be part of antenatal care in hospital or at home by the midwife, then it certainly wasn?t done with me. Firstly, when being told on day one in hospital (or, in fact, day 0) that I was to formula feed because baby wasn?t latching and was low birth weight, they asked me ?What formula do you want to use??. I said I had no idea, I didn?t know the difference, could they recommend one, aren?t they all the same, and ?I thought the difference was just marketing?? The doctor and midwife looked at each other, and you know, I don?t think they even said anything. They went and picked one and brought it back. On being discharged from hospital, distressed at not being able to feed my baby except small amounts of EBM with a syringe and formula with a cup/syringe, I was given an A4 sheet on how to cup feed. The midwife, understanding that I was upset and didn?t have bottle equipment at home (I hadn?t bought any, never for one moment thinking that I?d leave hospital not BFing) gave us soem syringes, a cup and a few bottles of formula and said ?I?m not supposed to give you these ? if anyone asks, they slipped into your bag?. The midwife the next day advised me what bottles and sterilising equipment to buy, and DH hurried to the shops and bought some formula too.
Re the card idea ? interesting idea, because as far as I see it, there?s no way to choose the formula you use and make comparisons. I?m still totally clueless on the differences between them (and are they so different?). I do now know about the ?follow-on milk? con, though, from Mumsnet 
Cardamonginger / Toddlerwrangler ? again, I think we have similar experiences :(
I?m not sure what the answer is either, but I think soem sensitivity is needed because it is very hard to be constantly asked ?are you BFing??. I wish people just didn?t ask. I feel like i have to justify myself all the time too :(
