The mother-in-law visits once or twice a week, as mentioned in the text: "She comes over once or twice a week, which in my opinion is way too often, but it's when I'm working (I work three days a week from 5 to 11 a3.m.), and my husband wants to sleep in."
The mother-in-law has not consistently followed the agreed bedtime routine. She has refused to learn the routine and often criticizes the child's behavior instead of following the established process. This has caused frustration for the parents as they feel that she is not providing the support they need.
The mother-in-law's house has several safety concerns for the children, including choking hazards left out in the open, a large and aggressive dog that is not crated or locked up, and inadequate cleaning. These issues pose risks to the children's safety and well-being when they visit their grandmother's house.
