We also go with want, need, wear, read and always have. I do worry reading some other posts that the world has gone mad with child centricity. How spoilt are some children going to be and how does a mountain of stuff they don't need make their lives happier or help them understand the meaning of Christmas?
I do stockings which remain fairly constant. A satsuma, some chocolate coins, a chocolate orange, socks or tights, knickers or pants, hair elastic, toiletries - nice shampoo and conditioner or shower gel. A book. A magazine or comic, something silly like a joke or kazoo. A DVD or computer game. £5.00 colouring pens or stationary.
My husband does main presents and is somewhat indulgent, in my opinion. Things in past have been new upgraded musical instrument (expensive but needed anyway), Mac books on entering sixth form, bicycles, a sewing machine, a Wendy house, a climbing frame with swing, new high sleeper beds, dolls pram and high chair, remote control car, PlayStation. They only get one real biggy.
Then we do needed stuff that gets an upgrade as it's a present - coats, boots or shoes, foreign currency for trips, military uniform upgrade, suitcases or rucksacks.watches. School bag or handbag. Nespresso coffee machine. Sailing gear, rugby gear, fencing gear, ballet gear.
In total I would imagine we spend more than we should but much is stuff we would buy anyway. About £5,000 in total realistically - but that's for six children.
