My son spends alternate weekends with his Father. Last weekend he returned on Sunday at the normal time and Father said he had been ill since Saturday morning with an ear infection. He had been taken to doctors and had medicine. I said that I should have been told if he was that poorly. Father said that I don't tell him anything. I said that I am primary carer and should be told. He asked 'what would I have done, come and picked up?' and then again said that I don't tell him anything. As primary carer should I have been told about this?
