I can deal with her 'need' to bath DS 3-4 times each day she has him as yes he will find the muddiest part of the garden/ spill his dinner etc and she is a little bit OCD about cleanliness
I can also deal with her 'need' to read him bible stories I will be telling him that they are fairy tale stories and in no way fact
But I can't deal with her 'need' to inform me that DS spending time with my brother and his DH is wrong and that I'm damaging my DS by letting him be around homosexuals
DS is apparently going to grow up to be just as confused as my DB if I continue to let my DS see him 
I may have become a little bit pissed off and may have mentioned that my DB and his DH will be our DSs guardians if anything should happen to me and DH. MIL didn't take the news very well bit of an understatement-
But AIBU in not wanting her near DS I don't want her to fill his head with her silliness I know he's only 1 so isn't likely to understand what she means and I'm probably being a bit PFB. DH thinks I should over look it to keep the peace but I really don't think I can.
