Comforting friend ideas

A friend just shared the news that she just lost her baby at 20 weeks. I’m heartbroken for her and want to find a way to provide support. I was thinking of sending her something as a way to comfort her and would love some ideas and general thoughts on what is appropriate or not appropriate. Are flowers or wine ok? Should it be more of a self care package? Should I give her some time before sending anything? What do people think?
