From another perspective, I was around when my siblings were born at home when I was 2, 5, and 12. I'm pretty sure I was sleeping and playing in my room through the first one, though I did get to cut the cord and I am told this was very exciting for me. I remember being familiar with the midwives and climbing in to my mom's bed afterwards, and wanting to use the midwives' blood pressure cuff on my stuffed cat... I also asked my mom to read me a story but she was too tired (obviously

) so I think my dad did instead and that was about it.
For my second sibling's birth when I was 5 and my brother was 3, my mom was in labor all day and into the night and we played by ourselves the whole time. My brother actually potty trained himself on that day. I still remember the shirt I was wearing. What someone else said about kids sensing there is something special going on and behaving differently is definitely true. Again I remember a familiarity with the midwives and the feeling of waiting, though no trauma from noises that my mom made. I also got to cut the cord this time and again I am told this was important to me. For a time after this I would pretend I was having a baby every time I was on the toilet. I knew it had something to do with pushing

For the birth of my last sibling I was 12, my brother 10 and my sister 7. I and my brother were present much of the time, also at the actual birth. My sister, I believe, got a little freaked out and left the room but soon came back to see the baby. We were older this time so could understand what was really going on and participated in the moments immediately after our brother's birth (cutting the cord, getting to hold him, taking pictures). Again our midwives were familiar and comfortable to all of us. We had tagged along for most of the prenatal visits as well so were really participating in the whole process and this was important and natural for us. This birth was particularly important to me because at the time I was just turning into a woman myself, and I got to see a mature woman giving birth naturally and on her own terms. She was in pain, but it wasn't deadly, and it had a purpose. I got to see that pain is not the greatest evil in life.
All of my siblings (except maybe my youngest brother because he has had no exposure to it) are vocal supporters of homebirth because of our experiences. I have talked with my sister about it and she agrees with me that she just couldn't imagine giving birth in any other way. Having your kids around as you build your family birth by birth is the best way to show them that birth is a natural, safe family event and to change the birthing culture slowly but surely.
