She frequently goes to bathroom (ensuite) then comes out of her bedroom frequently (every 45-60 minutes) probably up until 3 or 4am. I have mentioned there’s no need to worry about us as we go to bed safely. We can be in bed and she still will come out of her room. She said ok and she will stay safely in her bedroom but she still carries on behaving the same way. This has been going on for about 3 weeks and so is quite recent and new. She will also say that it’s her first time she’s been out to check when she’s actually done it multiple times. We are in our 50s and she is 76. Should I be concerned?
