MIL Issues

Anyone having difficulties with their MIL? Mine has been visiting for 7 days now and she flies home tomorrow and I hate saying this, but I'm counting down the hours. She has been arguing my parenting every step of the way and does the thing that bugs me beyond belief **when giving my son any food she shoves her fingers in his mouth** I have asked her again and again to let him grab his own food especially since I never see her wash her hands 😡 I have had 3 anxiety attacks since she has been here and my husband doesn't want to deal with her so he puts it on me. I have a full tank and am so ready to take her back to the airport 5 hours early if I can
