My friend had a stillborn daughter 5 years ago, before we met. I've known her for a few years now, and would say we are quite close. She mentions her DD to me fairly often in conversation. Her DD's birthday is the day before my DD's and I would like to send a card, is that the right thing to do? Also any advice on what to say in it would be great. I am worried about upsetting or offending her but I have read on here that parents like their children to be remembered so I just want to mark the day a little bit. TIA
