L.,
I'm due March 22, and am planning to deliver at United/Childrens Hospital. I've taken several breastfeeding classes there and they have a breastfeeding shop that carries lots of equipment and is staffed with lactation consultants. Most of the hospitals around here seem to be pretty supportive of breastfeeding, with on-hand lactation consultants and a daily breastfeeding class so you can bring your new baby while you're still in the hospital. Of course, I haven't had my baby yet, so I don't know about the care after your birth! And there's always La Leche League, of course! I'm sure there's an active group in your area, but if not, I've just joined the Apple Valley group, which seems very active and welcoming. You can get in touch with them through the LLL website.
Good luck!
J.
