Also trying to reduce and be more ecologically responsible.
In stockings I give
edibles (sweets I wouldn’t normally buy, chocolate coins, an orange, maybe a chocolate Santa)
Clothing - funky socks, t-shirt, hat, scarf, gloves.
Bath products - bath bomb, funky soap, bubble bath
Stationery- whatever they are running low on for school.
In terms of toys I compromise on stuff like lego and collectibles that have good second hand value, as they will eventually be reused. And if I can get it second hand then all the better.
I use comics, colouring books etc to bulk out the stocking.
