I got to watch once when I was in civil duty (I did my time in the surgery - great experience)
I actually pass on watching anyone being operated on when I know the people.
Weird, as with strangers, nothing fazes me - give me gaping stomachs and cut off legs for all I care.
So no - I did not watch, but I was present, holding my wife's hands and giving her the baby for a short while after the first checkup.

When my 2 yr old son was in the hospital recently (pneumonia, he's fine now) they were drawing blood and I saw it, but I was too busy singing Twinkle Twinkle and trying to get him to keep eye contact with me while they were doing it. My husband, on the other hand, was watching the nurse and what she was doing and he got white as a sheet and pasty and sweaty and he almost passed out. I was like "WTF DUDE, you're all stoic and my rock and you almost pass out at a little blood?" He also jumped down the poor nurses throat when he thought she was being too callous. I was like dude, pull yourself together.
When bad things are being done to our loved ones (especially 2 year old loved ones) we get a little crazy and our body physical reacts to the situation (even if we mentally know it's for their own good) weird huh?
