Growing up, we each got half a fruit bowl in our stockings - there were always loads of golden delicious apples at home, but not a lot of other fruit and it had to be shared and rationed between us all so this was always a real treat.
Red apple, green apple (Granny Smiths!), orange, mandarin, perfect banana, often a kiwi as well.
Always a 1lb box of sweets, and everyone got a different type.
Always a book.
(And those 3 continue whoever leaves out a stocking in DPs house! Youngest DSibling is now into his 30s!).
Then there would be a few small items - maybe a jumper knitted by DM for a Barbie doll, or a matchbox car, or some new crayons just for you!!
In my house now, DD gets - half a fruitbowl of fruit and some sweets. A book (or 2/3 - a reading book she'd enjoy, maybe an annual and maybe a kids reference book). Something useful like fancy knickers, hair bobbins, socks, a magic facecloth - something that she will use but maybe a step up from what we'd normally buy (e.g. character instead of plain).
And then a few bits and pieces that are more fun - some are educational too but fun - over the years we've had things like a small lego set, a crystal growing set, gardening tools, baking set, transfer pictures, temporary tattoos, twistables (the holy grail of colours!!), matchbox cars, kids binoculars, spinning tops.....maybe 4-5 small things that she'll enjoy.
