I was breastfed for 6 weeks, then on to formula as that apparently was the thing to do back then according to mum.
I'd never really been exposed to b'feeding before, my two SIL's never b'fed, they used some lame excuses as to why they never did, and were always asking me when I was going to wean DS, so obviously this nor my mum had any bearing on my wanting to breastfeed for so long.
