I am a mum of two whose ethos, I would say, is pretty sympathetic to "attachment parenting". In my view, we are basically mammals, and natural birth, breastfeeding, co-sleeping and baby-wearing are all normal and natural things for mothers and babies. Here's the thing, I am also a qualified paediatric nurse.
If we look at what we as parents are actually trying to achieve - healthy, happy adults - we need to ask ourselves, does this have to mean sharing our beds with our children or letting them self-wean? I think not. Because what really matters, what is really absolutely crucial to healthy child development, is not 'Attachment Parenting', but 'Responsive Parenting.'
