You should call when it feels right to you. This will usually be when you are in active labor as confirmed by your doula, midwife or doctor. However documenting your entire journey is important so it’s better to err on the side of early than late. The further a Mom is in her labor, the more she will want to rest, lay in darkness and labor uninterrupted so photography becomes difficult. Every client is given a set of calling cards to keep on hand that cover when and where to call.
