xpost Jelly - yes you are on the button.
Ok, my recollection is that I generously shared the ulimate tragic story about my DD's death to illustrate how dangerous cp coudl be.
SGB replied - yes, your DD dying is sad, but very rare, and it is unreasonable to stop people going about their daily busines just cos the odd child here and there will die.
I actually think that's quite rude, SORRY, VERY RUDE but to say it directly to a bereaved mum is actually 
I wanted to reply that it doesn't matter how many children die, if the one who dies is yours. What better way of illustrating this then putting it so personally, as to suggest the improbable event of both her children dying - as a basis for a fun future discuyssion on risk.
It shoudl be pointed out, that this remark was intended to make SGB and others think about the impact of losing a child - which is the same if it happens to you however small the risk was.
It did not increase the risk of SGB's DCs (if she has any) dying.
Whilst people seem aghast that I might theorise about SGB's living children dying, so many posters seem to think it is fine to expect me to appreciate that my intensely personal story is a bit off-topic because the risk of it happpening to anyone else is very small.
Some people here need to go and take a long hard look in the mirror.
