Dear Deb .. this is a dangerous stage. It was while my Mom was wandering around my brothers house in the night that she fell, broke her hip, never recovered. 2.5 years later she finally passed away after spending all that time in wheelchairs or bed.
I too am so happy for you that you got your parents into a safe place before this wandering appeared. It is usually a temporary problen but while it is going on it can be so scary and dangerous. People have wandered away and been lost, found on dark highways in the middle of the night ...
Thak God you got them both safe!
love,
Martha
