Not sure how to word the title

We have a wooden advent calendar in the shape of a stack of presents. We first used it last year but I had no idea what to put in it for gifts - staying away from chocolate as much as possible! The boxes are quite small until you get to the 24th & I was able to put in there a mini snow globe. I was wondering if you lovely ladies & gents had any ideas for me this year. I have to fit in 2 gifts or one at time as DS2 16mths is sharp as a whistle and will not miss a thing

Thanks in advance
