That is definitely the worst moment is life, to loose a child. It is against nature, parents are there to protect and to heal and to "catch the bullet for their kids".
Sons and daughters are supposed to bury their parents one day (when they are already long grown up) and not vice versa.
A nephew of mine died in a motorbike-accident, being in his early 20th. However I think it is not the same loosing a nephew or an own child. The pain, the suffering, the grief a parent feels with a kid dying/ lost kid cannot be imagined by someone not in the same position, I imagine...
Just thinking that one of my 4 (healthy) children could have an accident or happen to get seriously sick (without me being able to help them!) drives me nuts.

The best moment in life was the birth of my youngest daughter, as I was present and the first to hold her (after the Doc).
Next best moments are when I can sooth her pain by simply taking her into my arm, singing a pain-reliever-song, or bringing her to bed, reading always the same bedtime story and singing the same good-night-song.

Another bad moment (far not reaching the worst, of course) is when I have to leave for another business trip, kissing all of them good bye, hoping to be back shortly but knowing that the return-flight is not fixed...
