My dds are 10 and 6 at christmas. I've gone on the toys for a pound website and bought lots of stocking bits. Such as sand bottle maker, monster high vinyl figures, stationary, spongebob swimming toy, various blind bags, teen titans toys.
I always put a beanie boo in the top of the stocking - this year a narwal and sloth for dd1 and unicorn cat and llama for dd2.
I've bought dd1 various pusheen and Harry potter merchandise from Primark or reduced in Claire's accessories. Fleece blankets, new cups with straws, snowglobe, stationary, backpack, swimming towel/bag/goggles.
Photo frame with photo of a fun day out - DD's love this sort of thing for their room.
Adult colouring books and Sharpies go down well here. We have Harry potter, animals and Pokemon ones.
Nintendo 2ds is used loads by both DD's. Can get good deals second hand - I paid £30 including 4 games. They like Pokemon, legend of Zelda and Mario games.
Amazon fire tablet also used alot by both dds. For homework, reading and playing games.
Dd1 loves graphic novels especially the Simpsons, adventure time, teen titans and Pokemon. Or the Phoenix comics and beano are good too.
