My ds is 15 and for the last 4 or 5 years, I have done him a homemade advent calender with activities like ice skating, North Pole breakfast etc some days and other days a book or surprise or maybe just a sweet. I also put things in like 'Do something kind for someone today' Ds Still loves it but it's getting harder. He still enjoys the treat and some activities but I need some original, age appropriate fresh ideas. Any advice much appreciated!
