I was talking to my sister in law yesterday re babies. My niece is a year younger than ds. I had a homebirth (mostly) no drugs, breastfed, coslept from 6 weeks, weaned at 6months and did babywearing (slings) for most of that time. Ds had colic and didn't sleep well, was quite slow to walk and talk (although he was amazing at babysign) and was a bit of a sickly baby in general.
My SIL had a caesarean, bottlefed from day one put dn in her own room right from the start and did cc at about three months and weaned at four months, they never even owned a sling. Dn has always been a calm happy, healthy baby, she slept through almost from the start and walked and talked really early.
The funny thing is that I am not planning to do anything differently but SIL wants to be more touchy feely next time. It just goes to show that there is no right way to bring up baby, (although lots of wrong ways - did you read that thread about putting baby to sleep on their fronts because they sleep so much better ).
