How interesting that some of you have decided that I am a MIL who has been interfering in her DIL's life and that the post touched a nerve- nah, sorry to disappoint on the "touching of the nerve" but as someone astutely observed "your name rather gives you away" - YES I bare my soul to you DILs - I am a MIL - but I am also a mother (obviously) grandmother, wife, sister, aunt, cousin, friend.
AND I have an excellent relationship with my 2 dils - but then I'm a wonderful MIL
I don't transgress in the way the OP's MIL does, I never take pots of flowers, mess with the rockery, (still wonder what they did at the rockery!) clean windows, mow the lawn, paint sills etc etc. BUT I do help out, less so now all the grandchildren are older, but I used to meet them from school as parents working full time, and I was allowed to get their tea, empty the dishwasher, do shopping, get a meal for the parents, and even venture into the garden to get in washing!! BUT here's the BIG one - I often used to pick up nice M&S food for them (making sure of course that I bought veggie stuff for my DIL ) and stuff for the others AND I used to put it in the fridge!!! AND guess what - my son and DIL were pleased - "Ooh lovely" says my DIL "thankyou Nina" (and sometimes a quick hug) - imagine that a DIL who wants to hug her MIL.............
With my other son and DIL they live much further away from me so it's a bit different, (we look after the kids in the holidays) as both parents work full time and this works well for all of us. It means when we visit we stay over for a week. I always do the ironing when we visit (but only my son's shirts of course
and that's appreciated. I'm allowed in the garden too, and I put washing out to dry if it's in the washer!! That's about it........had to smile at the MIL who altered the blinds. My DIL has the blinds sort of half closed and I love daylight but I'd never dream of altering them, but confession time, once we had the kids while son and DIL went away for a few days and I did pull up the blinds. So YES I deserve to be lambasted for that - not respecting my DIL's wishes, but they were back in the usual place before they returned!!
OH and I notice now the OP's MIL is offering to look after the children (but only because they're bored of course) not because they love their grandchildren or want to help out and know the high cost of child care.
OK confession time.........I come on these MIL threads to show a different perspective, because I notice that almost always on the AIBU MIL threads, so many DILs pile in to assure the OP she is NBU and go on to tell her what to say to the MIL in question, often very rude and inflammatory comments and treating this woman like she's a child, which I find particularly unpleasant. I do wonder if these DILs are ones having problems with their own MILs - but who knows. We are but anonymous people tapping away on a laptop (in my case, cus I'm too old for a smart phone or tablet)
Anyway must go now - want to pop over to son and DILs and check their rockery
