When I was having my fifth, my eldest dd wanted to be present, she was 10 at the time. Well, it turned out to be a very rough birth, not what I wanted her to witness as a first experience, and she asked me so many questions and talked so much I had to ask her to leave.
The little ones were in and out, and did much better. they just looked, kissed me, and left.
Another birth, I think my fourth, the other three, plus my two younger brothers, were peeking through the bedroom window! And came running in as soon as the baby was out.
I've attended births where other children were present and they did just fine. One that stands out was an 11th baby, the 9 children still at home (eldest was away at college) were in attendence, and sat quietly and watched. Until the baby was out, then they all rushed over and knocked us (midwives) out of the way!
