My 18 year old has recently got a apprenticeship and is earning £300 a week, sometimes more if he works on a Saturday. Hes paying quite alot on his car insurance due to a accident ( his fault). First of all I wasnt planning on taking lodge / rent for the first year, but he seems to be spending money left right and centre. Im on my own and work full time in a minimum wage job. Ive asked him to pay £25 a week is that unreasonable?
