Hello @Claire P, you are welcome here and I hope you find the forum to be a friendly and supportive place.This is something really helpful. Thanks for sharing in such detailed manner.
Just want to say thanks,
Do take a good look around the site as it is a goldmine for information. When I first joined I read old threads for information but then found the AS Publications list and the page where a post code search can be done to check for support services in ones own area. If you are interested in these, clicking the following links will take you there
https://www.alzheimers.org.uk/get-support/publications-factsheets-full-list

You will see that there are Factsheets that will help with things like getting care needs assessments, deciding the level of care required and sorting out useful things like Wills, Power of Attorney etc.
