Good plan to get a doula, I wish I'd had one for my 1st baby. The Doula UK website has a list of FAQs, I found it useful when calling and meeting them. My DH and I learnt a lot from meeting the doulas. Try and see 2-3 if you can. I liked all the doulas I met but with one I felt very calm and relaxed around her, so chose her. Good luck.
