Sorry that's a rubbish title but don't know how to phrase it.
FIL with mixed dementia living "independently" in assisted living - medication given daily and a companion once a week to help with shopping/do some washing. Main food shopping and washing done by myself and dh. He can still dress, cook for himself and is generally fit and healthy.
He visits MIL every in her care home walking there everyday. He is only allowed at certain times 1100-1400hrs as there have been issues with the arguing - usually fights over money.
Something has changed this week that has changed his routine. I am not sure whether the clocks changing has knocked him. He's started getting more confused and the duty manager at his apartments phoned us and said the dad wasn't home and it was in the evening. We managed to call MIL's home who said he had just left so he was visiting in the evening which was unusual.
Just some things we are putting into place - we have the Herbert Protocol already to go just in case. We are telling the assisted living manager to try and get him to visit her after he has his morning medication. We are putting poster frames up in his kitchen and on the back of his front day - saying xxxx is safe and at her nursing home. Please visit her between 1100-1400 (do not turn up later as you will be turned away) and do not go out in the dark. We have also ordered some apple air tags to put onto his keys and add to the shoelace of his boot. He sometimes turns his phone off so find my phone won't work.
Is there anything else you can suggest?
