How angry would you be: DP's mum just arrived with his Nan without arranging it with us. I am 7 weeks pregnant and having very bad morning sickness, she knows this. They arrived during DS's nap time, I was asleep on the sofa- front door opens into lounge. MIL has a key for when she looks after DS. I feel like shit and was on the sofa in my tracksuit trousers and no make up on. She had tried to arrange something with DP yesterday and he wasn't keen, she said she would call him back. He tried to call her at 11:30 and she didn't answer, just turned up at 2pm.
Background: we do not have a close relationship with DP's Nan, a visit from her would have meant lots of tidying up and getting ready had we known. MIL is very helpful and adores DS, sometimes is blind to others in persuing time with him but we are appreciative of her and get along well generally.
I think that we need to be very clear that this is not ok and should not happen again. DP is worried about rocking the boat as MIL looks after our DS one day a week whilst I am at work.
