first of all you have to tell him that if he continues to treat you in this manner that he will not be allowed to pick up and he and the bio mom will have to sort out how to handle pick ups. I suspect that bio mom will not want to lose you because of his behaviour. as far as him not looking after the child when he isnt working, in all honesty its not your business as long as you are paid for the day. I realized that you feel that its in the childs best interest to spend time with hi parents but those are your values, not necessarily his. I personally dont care if parents take a day off and leave their kids with me as long as I am aware so tht I can reach them if I need to.
