What does your order actually SAY?
My order says we must confer about 'major' medical decisions, but that we're to each make routine and minor decisions while the child is residing with us. Mine also requires us to inform the other party about any medical issues noted while the child was with us.
So, when my 10 year old got glasses this year, I informed stupidhead that she had been to an appointment, and that she required glasses. I also informed him that I'd already ordered and paid for the glasses and that she only needed them for reading.
A dental cleaning is routine and minor. A tooth extraction would not be. Glasses - routine and minor... laser surgery - not so much.
