I wasn't trying to argue about what should be the baseline. If you want to use breastfeeding as a baseline, that's fine, as I said halfway through my post. But if you're using it as a baseline, then you can't talk about the positive effects of breastfeeding because that is your baseline. However, many people, including some posting on here use the baseline of an 'unfed' baby, ie not considering the effects of breastfeeding or formula. That is why you have people saying "breastfeeding gives EXTRA immunity" etc etc, because it's not being used as a baseline.
What you use as a baseline is irrelevant, you just have to bear in mind that your baseline changes the statements you can make. That probably wasn't very clear because I didn't use the word baseline (good word, thanks). But what I said was that if you use breastfeeding as your baseline you CAN say formula has a negative effect, but if you using an (and this is the only term I can think of) 'unfed' baby as your baseline, then you can say that breastfeeding has a positive effect. My main point was just that you can't say both at once, because then you're using two baselines together. They haven't proved in any way yet that formula feeding has a negative effect (from the 'unfed' baseline).
There are always extensive studies going on about the effect of formula on the immune system, to allow the manufacturers to improve their formula. Ok, they might care more about profits, but who's going to buy the formula if it's shown to be harmful?? I haven't got too much time on the PC right now so I can't look up the studies now but I will try to in the next couple of days.
Tissy - I don't want to convince myself that formula is better, I know for a fact that breastfeeding is better generally for babies. Or to use breastfeeding as the baseline, yes formula is worse for babies. However, that's still only generally. I didn't start formula feeding because I looked at the general stats and decided formula was healthier. I went onto formula because for my individual baby, formula was overall a better choice, for many reasons which I will list if anyone wants but this post will be long enough already. I'm not trying to use the wrong baseline to make a point, I'm just saying that the baseline you use affects the statements you can make.
tamum - the thing about the wet nappies is true and for a very healthy baby it works fine. But when I was breastfeeding, my baby didn't wet her nappies much. First of all the midwife treated me like I was stupid and said that I wouldn't be able to feel if they were wet because the Pampers I was using were super absorbent and would lock it all away. Then when I pointed out that I was judging by weight and they weren't much heavier than a fresh nappy, she told me it was because dd was drinking just what she needed and holding on to it all!!! Which was utter s**t. So nappies aren't all that helpful if there is a problem, however small. Whereas seeing milk go from a bottle does always let you see exactly what goes in. But that's not a reason to switch to formula, it's just an extra reassurance.
I'm NOT trying to argue in favour of formula, I just think that breastfeeding has so many benefits anyway that they speak for themselves without having to be rammed down people's throats. My point all along has just been that I don't agree with the facts being "rammed down people's throats" like that and I don't see how it will help the breastfeeding cause much. What would really help is better human support, such as better midwife support in hospital etc. I know some people have brilliant midwives who make it easy to breastfeed but that's not a standard across the country. I think that's why the bf'ing rate is so low here compared to other countries.
Formula is just a welcome alternative for a lot of people but why should they be made to feel bad just because the support wasn't there, or there were too many problems, for them to continue breastfeeding. Years ago, if a mother couldn't breastfeed, midwife support would have been a lot more intense, which must have helped, and there were even wet nurses in case you really couldn't feed your baby. Formula is the modern day replacement for this and while it's sad that there needs to be a replacement for human support, it's what we're stuck with.
I have got to stop doing such long posts!! I should stop having so much to say!
