I think writing a letter is a wonderful idea:) poetry is also a great way of expressing your emotions.
Also, what Enya’s saying is true. Having a memorial helps some women cope, We kept our daughter’s remains and buried them in our garden, then we planted a tree above it, as a sort of ‘grave stone’. Some mothers also light a candle on the day of the day their baby should have been born and keep it burning for 24 hours. I’ve also heard that art, gardening and keeping a journal have helped women deal with their emotions.
Love and hugs for all the mommy’s to angel’s in heaven,
