Many of my younger siblings were born at home, under the care of a midwife. The other siblings were present and it seemed to be a positive experience. My sister, Hayden, was 3 or 4 when she was able to watch her sister, Erin, be born. It was a special family time, and a completely positive experience. If things get crazy in the delivery room, you should have someone that can take the kids to another room and be with them.
