How can I give my friends the best support possible?

[MamaBones]

My friends birthed a beautiful baby boy on Sunday... who was completely healthy, however didnt start breathing-despite all the help from the hospital...
They have had him at home with them, hoping for a miracle...
It has come to the point where they realise he is gone now... and I just dont know what to do for them...
He was taken this morning by the funeral home, and they are starting to deal with everything this afternoon...

I cant even imagine the devastation they feel... My heart is just aching for them...

My question is... how can I give them the best support possible? I have never had to support a friend through loss before...

I am 32weeks pregnant myself, and I guess I am concerned how they will feel about having someone who is pregnant around, when they are grieving a loss of something I still have? I dont want to make it worse for them, iykwim...
