If you have a calendar of the sort which you can fill with your own treats, what do you put inside? We were gifted one last year so this year is the first year I'll be filling it for our DS aged 2. I thought about a mixture of 'activity vouchers' for things we can do together (e.g. crafty things, baking and so on) and some small sweets or chocolates but I'd love to hear what others do for inspiration.
