hi Zulfia,,, your question may invite various answers as per the nationality and financial and cultural background of the person who reply.

there are parents who spend 150 or 300 as pocket money. THere are parents who purchase very expensive mobile fones to the child. It depends on what type "posh" lifestyle the parents themselves show to the kids.

if the kid takes his lunch to school everyday, I dont think why he needs more than 100 per month. esepcialy in middle est, the kids follow us everywhere , all expeniduture are met by parents.

if the kids are interested to freak out in City cneter in group,,, it is diferetn story.
