Never would be my guess if they are all more or less grown up now,
As a child too young to handle money, I went with my mother to the shops and she looked at presents for my grandparents.
She would pick out one or two small things, and ask me, and later my younger sister, what we would like to give our grandparents, aunts and other grown-ups who gave us presents and who exchanged presents with our parents.
As schoolchildren we were given a little extra pocket money in December to use for buying Christmas presents and were firmly told that we could not come and ask for more!
Before going to the shops we made out a list each of those we had to buy presents for (including sister) and then did our Christmas shopping.
This way we learned early that giving presents is an exchange of gifts.
Nowadays a lot of children never learn this as they are included in the gifts their parents buy.
We were too, when we were babies and afterwards if the presents were to distant relatives or acquaintances rather than close relatives or friends. The gift tag would be inscribed as "from the X family" or " from Dr. and Mrs.X and their daughters."
