Comforting someone after child loss

My best friend just lost her baby last night, he was almost 2 weeks old. I’m at a loss when it comes to comforting her.. I’ve spent most of the day with her and just listened to her if she needs it but I want to do more for her.. has anyone else been through this or have advice on ways I can help her out. I have a 9mo and I just feel so awful for her and am trying to be careful with what I say.. I can’t imagine what she’s going through.. I can tell she’s still in shock but I can see and feel her pain. Thanks ladies.
