The truth is every woman should have a Doula at her birth, but not every Doula is a match for every woman.
You know about Google and gmail, but have you tried Google Voice?
Google Voice is currently a free phone number provided to you through your Google account. You are able to select your area code and pick from a selection of phone numbers.
Google Voice is an excellent tool for those who want a separate phone number for their doula or other birth business, without the additional cost.
