Thanks hun, I'll mention Linda Hay to her - would your friend know if Linda does any pro-bono work?
The cost is a big thing for my friend at the moment as she's struggling a bit financially. She's done a bit of asking around about prices but so far they've been out of her range and she doesn't know if she'll have the money to pay for a doula, although I have suggested to her that some Doula's would be willing to work out a payment plan with her.
