I start after the first Sunday in Advent.
I try to reflect what is 'new' with the age of recipient. So, one of our godson's got the new book 'Gaspard's Christmas' with a Gaspard toy. Another godson got The Dark Is Rising book because of the new BBC World Service drama.
I do the much maligned poem for our DC so just need to think of 4 gifts and I try to buy most of them second-hand. So, DD1 got a guitar from Marketplace as her 'need'. Grandparents add to DC savings with a token gift like a magazine subscription or jigsaw puzzle.
Stockings are a mix of apple, satsuma, sugar mice, choc coins, bath bomb/crayons/Tinti, Little Gems book, Guide/Scout Christmas badges and ornament, seasonal peg doll, a wee cuddly toy, YOTO card and other wee things that might reflect the year we have had. So, DD1 is into Harry Potter and I popped in Trivia Cards, DD2 is into Matilda so I popped in a card game.
The gifts are a small part of Christmas. I don't see the point in spending lots or getting stressed. It's about spending time together for the 12 days of the festival for us.
