DS attended DD's birth. He was 3 years 4 mos. It was wonderful, so glad he was a part of it. We watched a lot of videos, including some with kids. We talked about me possibly making noise, that my body would be working hard, like how you grunt when you lift something heavy. I did do Hypnobabies, expected a very peaceful birth. I would definitely have someone there specifically to care for kids and take them out if needed. Oh, we also talked about blood and why it might be there, but that mommy and baby would both be safe.
I had professional pics taken and he still loves to watch the slide show, a year and a half later.
