I agree that breastfeeding isn't just about milk- it is about comfort, reassurance and that 'specialness' between mum and baby.

I do think that by the age of 8 though, a child needs to be taught new ways of finding that comfort, that 'specialness' with mum. I don't think continuing to breastfeed an 8 year old to give comfort is the answer IYGWIM.
I agree.
