We did a photo book of DGD's life too. Front cover was her as a newborn and back cover a recent one. In between photos from each year-a great hit and she said there were photos she hadn't seen.
When her sister was 18 we did the same-in secret, of course, she said sadly to her Mum, our DD "don't think Granny and Grandad are doing me an album". This time we began with her as a newborn on front cover but then did a photographic family tree showing our Grandparents through to us then her Mum and Dad's wedding then her! That was a lot of work but very much appreciated.
It was so popular that their Mum, our DD, wanted one for her 40th-now that WAS a lot of work as many photos had to be scanned from old albums.
