I found this wonderful series on YouTube called 60SecDoulas. They are a group of doulas from the UK answering frequently asked questions in 60 seconds each! They allow their videos to be posted, so I'm adding them to my website to help answer my clients questions about my own services.
Like they say, every doula is different. I will stay with my client to assist in the first feeding and until everyone is comfortable and postpartum procedures are finished, usually about an hour, or until my client feels they are ready for me to leave.
