Am very sorry to hear this
My condolences to you both
I don't have any specific "advice" and am not a man, but I have experienced this, twice
All I can say is, much like eeore said, if she wants to talk, talk and talk and talk
if she wants to be quiet, don't badger her
don't ever let anyone say "it was for the best", "never mind, you can have another one" or "aren't you over this yet ?"
those things may be true, but this was your baby, another one can't replace it and it can take a very long time to come to terms with it
no rush to go back to work, either
I remember even after 2 weeks off, I was physically recovered, but the minute I walked through the door, I burst into tears
people forget that the bloke loses a baby too, so remember to look after yourself too, and don't take it personally of you get a
bit sidelined
all the best x
