Sue...youre comment made me lol...I can just imagine that...lol ;)
VVV and Harpsi...lol, too
Octo...to your questions...not that I am a professional, but will try to answer them as good as I can and hopefully people will jump in if I am spouting rubbish....feel free...
Infections...yes, partly there is more "danger" because Formula itself can be contaminated, as factory conditions and produce used may not always be aswell as they should, but also, because obvioulsy breastmilk itself has infection busting active ingridients...formula is a "dead" product, Breastmilk is "alive, full of enzymes and whatnot....!
As for Earinfections...not one hundred percent on this one, but I think that is somehting to do with the feeding position that can lead to infections...i.e. a Bottlefed Baby will be more upright, etc....but don't quote me on that.
And then of course all that counts for any infection goes for this, too...i.e. bm has infection busting properties....!
Braindevellopement, well, Bresatmilk is made perfectly for just "YOUR" Baby, Formula is produced for a massmarket, so, your breastmilk is tailored for your child needs, iykwim.
Also, again it's a life food and all teh ingredients are active and in the form that a human can best and easiest digest and there are all those fats in Breastmilk that are good and essentiell(sp???don't look right) for good Brain devellopement.
However, I don't think that anyone is claiming that Breastmilk will make a person more intelligent against other people, possibly more intelligent then they would otherwise been...because of course genetics and environment do play a huge role in this.
"I tried to bf my first unsuccessfully and switched at 6 weeks - bottlefed no.2 but planning to bf no.3 - neither of them have ever had an ear infection, rarely get colds or bugs, don;t have asthma etc - are pretty bright kids - so was it so bad to bottle feed them?"
Thing is, you don't know how they would have fared if they were breastfed...in the end breastmilk is the normal food for a human infant, Formula is an artificial product and often cowsmilkbased, and well, cowsmilk really isn't meant for human consumption, but is for Calfs only (dispite knowing that, I still liek my cowsmilk and can't get friendly with soymilk, lol)!
The Sids theory, as far as I am aware is based on again, the active properties in Breastmilk, but also, that breastfed Baby's often wake up more often and have the more natural waking pattern of a human infant. Artificial milk can extent the sleep periods and this can lead to the Baby falling into a deeper sleep then they meant to, and this can lead to them stoping to breath...however, they don't really know all that much about SIDS, so, it's difficult to gauge if this is the truth...it does make sense to me, but just because something makes sense doesn't mean it's right.
Oh, also, a Breastfeeding mother is meant to sleep lighter and "more" connected to their Baby and therefore may wake up esier in case of a problem...however, I know that certainly with ds 3 this was completely untrue for me, I bf'ed him, but was not bonded at all wiht him until much much later, and even if we co-slept I would turn my back on him (which apparently a bf'ing mother doesn't do...hm...), I also slept really deep...but, of course this could have been mainly because of my feeling for him after a traumatic Birth, ratehr then an issue of feeding method. As I am sure bottlefeeding mums bond just aswell...
May I just add this disclaimer: What I have written is not necessarily my personal opinion, just my conclusions fo the things that I read up on...but we all know 2 people can read the same thing and draw completely different conclusions, lol...and I am not a BFC or anything.
