I have had mixed 'luck' with Breastfeeding with my 2 boys... and to be honest, I believe everyone is different and that goes for every child / baby and mother.. I think that is why you can't give up yet!... With my first, he was a great feeder and I fed him until he was about 12 months old... With my second however, I could only feed him until he was about 1 mth old due to my milk not being great and him not putting on weight.. I am hoping to be able to breastfeed this one... I guess we will see..
... As far as the turned on thing, I dont think it ever happened to me, as the rest of the girls said, I do remember the uterus contracting feeling very early on.. but that is a little different to feeling 'turned on'.. I would suggest not to freak out just yet about it, and see how it goes.. Some ppl it works for and some it doesnt.. Take care
