My lovely friend and her lovely husband had their beautiful baby stillborn almost a year ago. They are still horribly devastated. (I know they always will be, but it's still very raw.) I want to mark their baby's birthday/anniversary, but I'm not sure how to do it sensitively. I would like to get some sort of keepsake, but I don't know what. Ideally I'd get tree or plant of some sort, but there are major allergies in the family which rule it out. I'm sorry to ask, but any suggestions/advice would be very gratefully received. Thanks.
