What should I do?

[Sundayscented]

Moved into isolation in mid March with my 90 year old Mum (who has to shield) at her house. Leaving my DH, adult daughter and pets at our house. DH & I are both retired.
We used to see her daily but since moving in I've realised she has been minimising/ hiding issues and needs more help. Help with: mobility, taking medicines, urinary continence, drinking insufficient water (repeated urine infections etc), coughing fits, repeated reassurance and help to remember things etc. Although at times she is very sharp. We've tweaked lots of things to make life easier and establish routines. GP is aware of health issues. Adult SS helped sort mobility equipment.
Our daughter has now had to move out for work so DH is on his own with pets. Our house is only a 2 minute drive from Mum.
If you were me would you stay isolated with Mum or go back to live at our house? I do miss DH and the pets and could do daily visits - but I wonder if I would be constantly called by Mum because there is a perceived problem....... so constantly on guard which maybe very stressful.
Oh and also I'm in the vulnerable group too (but not shielding!).
What would you do? Thanks

Couldn’t she come and stay with you?

Could you stay with your mother but do daily visits to DH and pets? If you were just visiting, then you might feel OK about switching your phone off for a couple of hours, and get more value from visiting than if you based yourself with DH and were on tenterhooks the whole time?

Could DH come and see you at your mother's some time? - once he's ha+d 14 days isolation. I see no reason, if you and DH are isolating, why you couldn't effectively join your two households into a "bubble".

Thanks for your replies. Unfortunately she can't live with us as she has animal allergies and we have steep stairs.
Mere - that's more or less what we/ I were thinking about combining households with the bubble concept. DH has been isolating for the last 7 days ready for daughters departure and limiting contact before that. Good idea about visiting there are turning phone off...... thank you again.
