I can't Handel anymore stupid!!!

Is my MIL the only one on the planet that doesn't know how to mind her own damn business?!? Like fucking seriously!

I had my son back in 2013 and me being a FTM I listened to her for almost everything. Well one day I was washing my son's bottle's and she came up to me and asked why I was washing them again and how washing it all the time could make him sick. I felt bad and she told me that all I had to do was rinse it out with warm water; so I listened and that all I did for a year, of course I washed them but I mostly rinsed them. Not realizing that not washing them with soap or boiling them can make him even more sick because of the mild dew that grew in them.

Fast forward to today...

He is almost 3 now and I still have to listen to her about everything because she lives with us! Yesterday she made a comment about how my son needs to stay off his ipad and blah blah blah. Then today she asked if he was awake yet and I said "yea he's watching his ipad" and she said "he needs to stay off that he watches it 24/7" I replied "no he doesn't he is fine he watches it till it dies(which it dies fast) then he plays" then she kept opening her mouth so I left. Then I went and bought my son a really nice used bed from a lady that came with a mattress that wasn't even a year old yet and she asked "why don't you use the mattress with the cover in the garage" that mattress has sat in my garage for 3 years 3 YEARS!! I told her "because it comes with one I don't need too" so she goes on about it I just ignored her and went on.

No matter what she is always in my business when it comes to my son; If I call him she wants to know why, if he is crying she wants to know why, if he is being bad she feel's the need's to open her mouth.

I can't do it anymore I'm gonna flip on her; It's not her place her business but she thinks she has entitlement somewhere!!
