Ask your doctor what the hospital’s policy is regarding how many people are allowed in the room and if there is an age restriction for visitors in the hospital that you plan to deliver in. This may effect who you plan on inviting.
Really consider the situation carefully and what will happen during the labor and delivery process. It may effect who you will want in the room with you when you deliver.
If someone comes to visit and you prefer not to have them there, let your labor and delivery nurse know how you feel, she can help.
