Consider this a journal you write in once a year. As a suggestion perhaps at the end of the year - or even on every birthday. Include your favourite photo for that year and write to your child. Summarise the year over three lined pages for 21 years and then gift it on their 21st birthday! A present money can't buy but the richest gift of them all. All the memories, all the great family times, all the achievements, all the emotion and the feelings, everything you want them to know and remember documented in this 21 years of keepsake.
