Years ago my mother made a cloth Advent calendar with laminated and pinned labels for each day for what Bible readings were relevant for the day and season. We inherited the labels.
A year or two ago my sister gave us an old Victorian style advent calendar box with little doors that open up for each day that goes on the wall. Originally it had candies in it but now it has the labels in it. So, each day we try and open one of the little doors and do the Bible readings for the day.
We have not ways been very good about doing the readings with the little boys. I am hoping that this year will be better. 😇
