When our girls were growing up we gave them a stocking and then later in the day a present from us. We mainly did the stocking to hear the fun first thing in the morning as we opened our main presents after lunch.
In the stocking were some fun things but mainly things that they needed for the year like undies, sock, hair things, pencils etc.
There was also fruit, a lolly or two, books, a small game etc
The first year of school was easy as this is where I could fit in things for starting school.
