You seem very kind and brave. I use the word brave because after my recent miscarriage I found that more friends than I'd expected were scared. Scared that they'd do or say something wrong, so they'd say nothing instead. It was a very lonely sad time. I am a midwife and I was pleasantly suprised at how wonderful and supportive my midwifery colleagues were. They weren't scared of grief. One friend would call in the mornings a lot because, having experienced the loss of both her parents, she knew it was most particularly the hardest time of the day.
So remain brave and send her a card or thoughtful present, you will make a difference.
