What an absolutely beautiful friend you are . When we lost our little Angel we bought a symbolic necklace that was engraved with details, maybe thats a bit personal for what you want to do? A gorgeous lady who is a 'bit spiritual' iykwim gave me a pink baby rose bush to commemorate our babe....I hadnt even told her I was pregnant or had lost our angel. If she is the kind of girl who might keep her pregnancy tests etc, what about a really lovely box to keep all those 'memories' in along with a notebook to write a letter to each of her babes? Just a few thoughts. Wish I had of had a friend as caring as you x
