We have noticed over the last few months that most of the time, if we didn't prompt her, MIL would still be in bed at lunchtime. She seems to get up to collect the paper from the front door, but goes back to bed. Nothing wrong with this but what's going on? What has caused this change ? Is she forgetting the time of day? Has she not slept at night so is tired in the morning? Is she "depressed" and can't be bothered to get up ? How will we ever know if she can't remember? Has anyone experienced this? What should we do? Should we do anything? Thoughts?
