Hi Trish, what a heart rending situation you and your family find yourself in. If your Dad is ill with cancer, he certainly can't cope with the needs of a dementia sufferer. He will find this so dreadfully hard, because he loves her so. If you can't arrange 24/7 at home, then a special home for those with dementia is the only answer I'm afraid. I know it sounds awful putting your Mum in a home, but they are not all bad you know. A friend and I have recently had to find a home for her parents, we looked at several, and the one we chose is really nice. Just shop around a bit and find one you are happy with. Then, when you go to see your Mum, take your Dad as often as he feels able. Enjoy little treats with her, take her out, do all the things she enjoys. Also give them a bit of time alone together, but not too long or he will want to take her home with him and that would be too hard for him to cope with. Make the time you spend with her quality time, it will not be easy, but your hands are tied by circumstances beyond your control. It will take time for your Mum to settle, so be prepared for a possibly bumpy ride at first. My friend's parents have settled in remarkably well, she is very relieved I can tell you. If you find a good home, your Mum will be fine. Thinking of you, love She. XX
