Mother in law keeps leaving her pills lying about and argues about it. We have a 4 year old and one month old baby.

Mother in law is staying over for 3 months to help as my wife had a baby a month ago. She is difficult and we have to put up with all sorts of nonsense. E.g. She keeps walking into the bedroom despite being asked countless times not to, it’s very annoying. Anyway the last few days she has been leaving her medication lying around. It happened before on a previous visit and my wife had an argument with her. She’s doing the same thing this time and arguing that our 4 year old won’t take them from the place where she’s leaving them. I’ve had enough but my wife is telling me to calm down. I’m going to tell her if she’s going to do it again then it’s better she leaves. My wife has told her not to do it again but they had they conversation before and she did it again regardless. I’m absolutely livid because she’s putting my children’s lives at stake. Any advice would be gratefully received. via /r/Parenting https://ift.tt/370ZzfQ
