S.B.
I think it would be worth it. I did not use one with my first child and if the hospital here did not have a limit to 2 people total in the room with me (since it will be my stepmom and husband) I would use a doula this time. My neighbor who is also a friend is a doula and it sounds wonderful all the stuff she does during delivery and after.
She can also help with breastfeeding...but you can also ask to see a lactation consultant at any time after birth.
Good luck! :)
