I hardly spent anything on dd when she was younger - probably about £30 or so when she was a young child. Picked stuff like bikes and trikes at auction. I was skint though.
Now she is nearly 16 I spend a lot more on her - I think you tend to when they are teens. Very easy to spend £20 on a small child - less so when they are older.
For the past couple of years I have committed the previously-hated crime of combining christmas and birthday presents for dd (her birthday is mid-December). This has been at dd's request. They have been things that she has really wanted and were useful, not just spending a couple of hundred quid on tat.
Last year - paid for trip to Berlin (£250) and blackberry (contract, so £180 over the year)
2009 - camera and trip to Paramore (£250)
2008 - ski trip (about a bloody grand when adding up salopettes and other ski gear)
2007 - laptop (£600 - she still uses it now)
2006 - pushbike - £200
This year she is getting a moped, so with the bike, paying for CBT, insurance, helmet, jacket, gloves that is probably a grand all told.
BUT - she is an only child, I have no family on my side, and only get small sticking filler type presents from DP's family.
And, I only really spend on dd. Me and DP don't buy each other presents, I don't buy for my friends (with DP and friends we arrange to go out for a dinner in a smart restaurant) and only buy for the children in DP's family, not the adults. The only other large present is for my 24 year old stepson, we usually give him a couple of hundred quid and some clothes.
So my christmas spending burden isn't very high really.
