well just thought id put in my 2 cents...
nobody is gonna agree what is fair and what isnt cause some ppl may say activites such as ballet, soccer, etc etc arent 'needed' and as BG said its to cover living expenses not social expenses KWIM?
needless to say i only get about $40 a month off XP but fairly often (depending on how much he has left over after spending his money on pot ) he will put another $10-20 a week into DD's account.

i guess that didnt really help did it lol
