My mum was horrified when it came up in conversation that I put half our child benefit payments aside to pay for our annual family holiday. The other half goes into a pot mainly for the DCs' clothes, and other odd bits they need. She thinks this money should be put into a savings account for them - which it would, in an ideal world, but there's no way we could afford to take them on holiday then 
I'm now curious about what other people spend it on, and if my mum is right that it's a bit unfair of me to spend it on holidays?? As I said, if I didn't do this then the children would have no holidays as we simply couldn't afford it.
