She doesn't understand what people say to her on it, then forgets what she does understand
. But doesn't know/acknowledge that its an issue. Obv Dad tries to get there first, but he's not always right there (and is v slow on his feet), and then it all gets a bit fraught. He was not cut out to be a carer, and is struggling with the new reality of her.
So any ideas on how to reduce the issue ?
