Several points from me :
The 'children' could each do it twice or so a week and would cover it.... It would take them a maximum of 30 mins to nip over in their cars. It is THEIR responsibility... So they're busy....well they need to re prioritise to help their mum.
It's way too personal a care task... And moreover you (rightly) DON'T WANT TO DO IT!
You're slipping into an unpaid carer role... It will worsen as you'll be perceived as this nice neighbour who will do anything to help our mum/deirdre.... IT WILL BECOME AN EXPECTATION,,,, that you'll be the 'go to person'... Like if she develops worse physical health or has a stroke /develops dementia.
You can still be a good friend /neighbour without doing these tasks!
More importantly you have YOUR LIFE TO LEAD as well as health conditions to manage yourself!
This ^ in spades...
You can do too much for some people, and they WILL take advantage, and WILL expect it. And the adult children will often be quite happy to let the 'helpful neighbour' do it too.
I know someone who befriended a woman he worked with (20 years older,) and when she retired (at 60,) he and his wife used to meet her for coffee, and go for lunch occasionally. Within a year of her leaving the workplace, he and his wife were being asked (by her) to help her move house, help her put carpets down, help her decorate her house, and take her to hospital appointments. She lived 40 miles away from them, and her hospital was a further 20 miles...
She had 2 adult sons who lived 15 miles from her. She didn't see them often, as they had very busy, big-important-man jobs.
When she started saying she wants him and his wife to deal with some general personal affairs and admin, and she needs a regular lift to the hospital once a week for the next 8 weeks, and could do with some gardening doing, the wife put her foot down. She said 'enough! She has 2 fucking grown sons. Whatever the circumstances of them rarely seeing her (just on her birthday and at Christmas,) it's not down to US to be her personal fucking chauffeur, servant, admin officer, and chief cook and bottle washer...'
When he rang her to say he wouldn't be able to do the hospital visit thing for 8 weeks in a row (120 mile round trip each time!) and due to other commitments, he and his wife wouldn't be visiting for a few months, and wouldn't be doing the gardening; she got snarky and nasty, told them to please their bloody selves. Then she changed her phone number and ghosted them.
Totally just using them she was. Didn't want to know them when they weren't being her personal servants.
