It is lovely to read such positive responses to the idea of the "What we did" letters and, if you want to, putting them all in a book. I think it is something good to do when your GC are young, even if you didn't start when they were born.If you wanted, you could write a letter with photos about what you remember about their life so far, and then begin with the 'what we did letters' at whatever age they are. If you take this idea up, you could learn from my mistakes. I only had the idea of putting them in a book as the first DGD approached her 10th birthday, and though I'd saved most of the letters on my computer, they were not all in date order and they were all in separate Word files, which meant a lot of work to get them into shape for the printer. So with hindsight, here is what I'd have done to make it all easier: save each letter in date order and separately. This is your back up. And also as you go on create and build a single Word document with all the letters in date order. You can tidy it all up and add an introduction, title page and anything else you want, when you are ready to get it printed - but this basic Word document will be the basis of the book and save you hours of work when you get to the time to print. Once it is exactly how you want it, you save it as a PDF (but keep the Word version too) and send the PDF to the printer. I hope this helps anyone doing this! Do not be put off - it doesn't require great computer skills; if you can write a letter on the computer, you can make a book, and you are not trying to make it look super professional. It is by and for family and is fine to look a bit home designed!
