Bm, school and paying for medical

Bd just had a phone call with BM. Ss lives with us (bd and sm) full time, but bm is supposed to pick him up today for an overnight visit. Ss has orientation this morning at his school and then an appt for new glasses this afternoon. She's going to have to take him to that appointment. It shouldn't be a problem since she also has an appointment at the same place at the same time (the provider is dhs family member). Well, during the call she asks bd 1)for money to pay for his glasses 2) if ss started school today 3) where his school is 4) the name of his school

Bd reminded her that she gets the same emails that he gets from the school. She claims she doesn't, he told her to call the school or check her spam folder. As for the money, ss is under my insurance so his co pay is $10 and his frames are free. Bd is not giving her any money for the co pay. Bm does not pay child support. She does not help with school supplies, birthday parties, holidays, clothes or any other medical expense including his weekly therapy co pay. Bm is supposed to he dropping ss off on his first day of school. Since she clearly didnt know when that was well see how that goes. His drop off is a full hour earlier this year that last year so I anticipate hell be late. 3 tardiness and he gets in school suspension. I think they need a different custody arrangement but that is not my choice or problem.
