At Christmas - on your kids.
I'm talking relatively speaking.
My DH and I have about £400 a month disposable income between us after all bills and food etc and we've probably spent about £400 on presents for one child this year.
My in laws think this is excessive but other than Birthday and Christmas there isn't many new toys in the year so this is an ideal time to provide with new age appropriate fun toys and we always donate older toys (that still work) to charity.
