When we lost Mum the counsellors at mary potter gave us memory boxes, in which there was a pad and pen to write down feelings ane memories, there was a little booklet about children and grieving in it, a balloon (to blow up, and 'send' to the departed with happy thoughts), and a few other things. Find some great photos, or if you've kept cards from your FIL, put them all in the memory box, and whenever Miss E feels sad she can remember the happier times ;-)
