@WollwunderPetra: How funny, my husband and I have the same tea calendar too, one each. For the past few years, we’ve done this every year: in the evening we have a cup of tea together and wind down the day.
I also took part in a shared Advent calendar in our village community this year. 24 people each make 24 identical gifts and are assigned a day. For example, I had day 5. Then everyone meets up, and each person takes a little bag from every day. That way, everyone has their own Advent calendar. If too few people take part, you can also do two doors per person (and, for example, agree that one door is just a story or a recipe or something like that, so it doesn’t become too much).
Our 2.5-year-old son also got an Advent calendar for the first time. For it, I sewed 24 little pouches and attached them to a branch. Every day there’s a mini fruit bar, a bath bomb tablet, or something similarly small inside. He’s delighted.😁
