Mere minutes. You simply navigate your way through the personalisation options, then you can review every page of your book to make sure it's perfect. If it's not quite right yet, you can tweak and tune it to your liking.

Yes, absolutely. You have total freedom to set the names that appear in the book – and the avatars' appearance, of course. The only real restriction is that it has to be three generations – so a child, a caregiver and a grand-caregiver. (If that's not a word, it should be.)

A multi-generational book might not teach them the Pythagorean theorem, but it does impart an invaluable lesson about the preciousness of family relationships. You can't buy that kind of bond.

We asked the unfathomably talented Jake Biggin to bring this story to life for us. Jake specialises in heartwarmably soft watercolour illustrations – the kinds that make grown adults ask if someone's chopping onions.
