Ds needs braces. NHS approved treatment so not just for cosmetic purposes. NHS waiting time (as not priority) is upwards of 2 years from initial consultation to first having braces fitted so could be 4 years plus before he is done.
Private costs are £2500ish. Exh has never contributed a penny over the CSA rate, I've struggled to provide for the kids and have juggled finances to accommodate most expenses but this is beyond my budget.
Should I (or how could i) ask the ex for some help with this?
