TRIGGER baby memorial??

So I had a miscarriage, 2 in my lifetime.. one last year on October 2nd and one this year on October 22nd. I was very early so I didn’t get a chance to get a scan photo or anything like that. myself and my partner are devastated. I wanted a shelf in my room to be in memory of our babies but what can be there? I want it to be special, warm... a place where we can feel close to them. I can only think of putting a candle but they deserve the best and a candle isn’t enough.
