What should I do on my baby’s due date?

I don’t know if it is too dark but I was thinking lighting a candle for her this Feb, 22nd. Writing a letter to her a then burning it. Do you think it is too creepy?

A friend that is also a priest said to me that unborn babies and stillborns were angels that God needed so badly that could not wait for their time in earth and that is why there was no need to do a mass in their honor, but I still want to do something meaningful so she knows how much i love her. Am I crazy?
