Mine are 5 and 3. They get around 7 presents under the tree from us, mainly toys, and a couple of books. They also get one present each from FC with their stocking - this year the things each has specifically asked for cost around £10.
They do get presents from others but it is mainly clothes with the odd game or puzzle.
Their stockings have around twelve 'things' like top trumps, cutlery, football cards, a book, small toy, something they need and some silly bits like whoopee cushions, mini pinball, kazoos, tat we never usually buy them. On top of this they get chocolate coins, satsuma, apple, tube of sweets, small box of cereal, chocolate Santa, and something they especially like. So dd is getting crisps and ds is getting a jar of marmite.
We don't really buy toys at other times, though we would update an outgrown bike or scooter, this feels about right.
