If you are uncomfortable being partially or fully undressed and making noise in front of the person you choose, it will hamper your ability to relax and do the work of labor. You should choose someone who is devoted to the task, able to put aside his or her own agenda, and is fully available to help and support you.
Too many support people can also have a negative effect – you may feel it’s too noisy or crowded, or you may feel like you are being watched.
In order to labor, a woman must feel free to move about clothed or unclothed, make noises and not be distracted from her concentration. One or two close, supportive relatives or friends who meet the above criteria are probably the best choice to help you through labor and delivery.
