SO mother and pictures with my Newborn

My BF mom is in town for 2 weeks. As soon as she came she gave my hiccuping newborn premie water(infant), wiped her butt, face and privates with same cloth. Tried to add more cushion to her bassinet for softness. She completely ignores me. Then she told my BF not me that she scheduled for us all to take family photos. I just had a c-section, still flabby, and my hair is a mess, as well as being broke. We don't always get along with her and she didn't even ask if that was ok. What should I do... stop the photos or go along with them???
