forget your hv's words about 6 weeks - where do they get this info from????
Check out the unicef babyfriendly leaflet that KisKidee has linked and co-sleep for as long as you both want.
I've co-slept & bf at the same time - lovely.
Also co-slept at the hospital - no problem. Beds narrow but then I just took up a really small space and blocked the otherside side with the cupboard.
