M.T.
The most important thing is to have that special adult whose job is solely to care for your daughter. Your daughter really only needs to be in the room once you are crowning, it is boring for them and distracting for you (and frustrating for them not to have mommy's attention when they are so tiny) to hang out for hours of labor. Smart as she is, at just barely two, she will not understand what she is seeing. I would only consider bringing such a young child if you are certain that she can and will ask to leave the room if she wishes. Please dont' get me wrong, I am a supporter of children at birth, I was a Bradley teacher for 13 years and a doula too, and fully support the idea of kids being at a birth if they have asked to attend. Good luck!
