DS has just left school, but for the last 13 years, uniform has come out of the £26.18 a month CSA calculation (no, tell a lie, he refused to pay anything for the first two years, said if I made him pay, he wouldn't see DS - should have taken him up on the offer). Fortunately, I could afford to support him on my own - just for the early years with a big overdraft and a credit card). Through school I have paid for every last pen, plimsoll, and trip, just as I will pay for the college bus pass next month, the A-level text books, and, no doubt, more educational trips to Rome, bloody Classics!
It is tough, and feels terribly unfair (I also know he won't be good for any help with university if DS gets there), but, DS has worked out for himself, who is reliable, who has his back, and who has been there for EVERYTHING.
