Friend loss here baby

Delicate

So my friend been pretty quite all week long after the baby shower but she called to check up on me couple days back. We usually hangout every week. So this morning she calls me telling me to sit down and I'm yeah I sitting down and proceed to say she loss the baby. How she loss the baby was the umbilical cord was wrapped around the baby neck twice and the baby was laying across and not head down. I asked her if she was okay and tired to do my best at telling her everything going to be okay. So there having a little get together for the baby Saturday which I'm going but I've never experienced anything like this so I was wondering what do I get someone who loss a baby?

Baby was a boy and she was 39 weeks already and baby was suppose to be here in week and half.
