My little boy lives with his mum and I decided to do an advent calendar for him but what I will do is leave a small box on the doorstep each morning with something different in it each day that I find. It will be a leaf or nut or something and then he has all day to find out what it is from books and then phone me at the end of the day to tell me what it is. I will text his mum the answer any way just in case they struggle. I thought it would be a better idea than those shop brought ones with chocolate in them. Today is an oak leaf to start with.
