will the fun ever stop?

Sweet face 82

My STBXDbag informed me tonight that he took it upon himself to begin giving our breastfed DS whole milk....without consulting me. He thinks that this will give him a better chance of getting overnight visits (DS is 1 year tomorrow).  He continues to be unable/unwilling to answer any questions about DS (like did he drink any water since he has been sick, are you finding his appetite is back to normal, what was his temperature), refused to move or alter visitation this weekend with DS had a 104 fever off and on, and his parents are in the car for EVERY pick up and drop off.  *Smacks forehead with heel of hand*
