Giving birth with your 5 year old in room

My daughter and have are very close and open, as much as you can be with a 5 year old. She knows where babies come from and how they form, just not how they are made. She has seen animated videos of progression inutero and birth, she is very intrigued by it and is dying for a baby in the home. Lol. She insist SHE is taking care of the baby. She will be nearly 6 or 6 when we actually do have a baby if all goes as hoped. I want her to be a part of it. I plan to have a birthing photographer. It's a special thing and I feel she would be perfectly okay. But I do have reservations about her age. Would you do it or have you?
