I have always bought my children (ages 3 & 6) "traditional" advent calenders. I had them up to being a teenager and have very fond memories of them.
Eldest has cottoned on to the chocolate calendars now because her school friends have them. She hasn't asked for one yet but I wonder if she will this year.
AIBU to keep buying the old-style calendars so that they enjoy the simple pleasure of the count-down to Christmas and wondering what picture they will get?
