elsie, find a way to not be around her. when she is coming by for the child then run an errand, go somewhere, take a shower, anything but don't put yourself in a position where she can get to you. i learned this trick with my husband of 23ys. he has an 11 yr old son (yes, not mine) and there is a court order for visitations with his mother as my step-son came to us from foster care. he mostly drops son off/pu so i don't have to deal with it. it's hard enough as it is. my storey some other time. good luck
