I think I am winding myself up about how cheeky I think she is being and the fact I have to have that talk with her. I just know she will say she was expecting x and now what will she do...
Then practise now. Do NOT offer runs to the hospital. Just 'Sorry for the misunderstanding. We are not in a position to offer assistance. We have far too much on just now. You will need to make other arrangements.'
'What will I do?'
'You will need to take up some of the help you've been offered - daycare. And call the social worker. And arrange taxi transport for his visits' (please do not do that to yourself emotionally).
'But that costs/is expensive.'
'It's unfortunate, but nothing in life is free. And we are not in a position to provide assistance.'
'But your husband said,'
'He offered to have him over for one meal. Not regular care. I'm really sorry for the miscommunication, but we are not able to provide assistance.'
She has the mind power to get her hands on monies - attendance allowance, council tax benefit, she can sort this out.
It really has to be nipped in the bud now.
I would ring her so she can't pin you down in person.
She's got a helluva cheek.
As for the hospital, if they ring you, set them straight.
