I'm obviously biased towards childminders (because I am one), but there will be plenty of mumsnetters who use - and are happy with - nursery care for their babies.
However,I agree with what the others here have said - I believe that a home environment is far more suitable for babies. However, you obviously have to visit a few to find the person you feel would be best for you.
Childminders tend to go out and about more - during my normal week, we go to a music group, soft play session at the local sports centre, a toddler group and visit the library, go for walks and so on. We go swimming, go out for whole days to farm parks, for picnics and so on.
Some parents prefer nurseries as they don't like the idea of their baby forming a close attachment to another "mummy figure" - but a baby does not ever see us as mummy, however long the baby might be with us during the day. I'm just part of their extended family!
Childminders are usually more flexible than nurseries - both with early starts, or unexpected late pick-ups (don't read all our moaning threads here!!)
There can be superb continuity of care. I have children who started with me as babies, and continued through the early years to nursery and through school.
Visit some childminders - you can find those near you via the Childrens Information Service here . It may help you decide if that's what you want. And visit some nurseries too (I'm saying that but don't really mean it!)
