I agree Swallows, I think any post natal service is going to be more successful if it can offer a "come to your house" option as well. I ruled out a number of breastefeeding consultants purely on the basis that they didn't do home visits and I couldn't get it together enough to get to them!
But perhaps there is room for a "one stop shop" to offer both, a cheaper drop in option and a more expensive come to your home option?
