OhBling, you've hit the nail so totally on the head - put it far better than I, in my crossness, ever could.
My MIL makes minimal effort to get to know her grandchildren, she wants them (with their combined age of 3.5) to know HER. She bangs on about how beautiful they are, bores all her poor friends with photos, and yet doesn't know how or doesn't want to engage with the children at all.
On the phone or Skype she rarely asks a question about him, instead says to my DS, "Do you want to come to Australia to see Granny's house? To see all the kangaroos? Do you want to come on a big aeroplane to see me? You tell your Mummy that Granny is going to come and get you and take you to Australia on a big aeroplane." Result is DS is bored and a bit freaked out by her, and I have to bribe him with peanut butter to get him to talk to her.
When she was last here, and DS was 2.5, she said she wanted to take him out in his pushchair for a walk. ME: Where to? MIL: I want to walk to the high street and get a coffee, and there are a couple of shops I want to look at. ME: DS will run amok in shops. MIL: Oh, no, I'll just keep him in the pushchair.
It took all the tact I had, and then eventually going up to DH and getting him to talk to her, to explain without causing offense that DS didn't want to be kept strapped into pushchair going in and out of shops for an hour and a half, wanted to do sliding, swinging, running round the place yelling. If she tried to keep him in pushchair for 1.5hrs he would, quite understandably, have a fit. Of course, this was racked up against me as eg of me not wanting her to spend quality time with her GS.
The point is, she wants to show them off, wheel them proudly about in buggy, she wants to feel all puffed up at having them in her life, but has no desire to actually make the effort to connect with them or put them first or even ask the most basic questions.
I know it's just life - I've been dealt needy, childish MIL, and the point is I love her son, so. But where it gets really damaging is how she uses the fact that they live in Australia to attack my marriage and make it v difficult for my DS to relax and be happy here.
And, as OhBling says, I can't shout at her. The only person who could shout at her is my DH, who is defensive and emotionally retarded when it comes to his family, so largely treats her like a broken little flower.
I didn't conspire to have PIL live in a different hemisphere. I fell in love with their son,he fell in love with me, we've made a life together. Both our careers are here, our lives, it's our home. Living in London is not an act of malice. But my arse MIL is successfully making my DH believe that it is.
Making myself furious typing about it. Cricket bats at dawn.
