These are all excellent tips for new caregivers, especially when it comes to setting boundaries. I read an article recently that talks about journaling as a way for caregivers to cope with their new responsibilities and stressors as they adjust to their caregiving routine: https://athomecarecompany.com/benefits-of-journaling/

Another excellent article covering so many issues that most caregivers are facing.
There is help out there that would provide information and resources to a caregiver. It might take some time and energy which is scarce when your a caregiver, but it would be worth every minute of your time. You would save your time and emotions in the long run, when you are prepared, get the support and get some meaningful tips from others.

@marymerry - It's like "The boy who cried wolf"! Does she "interrupt" even when you tell her that you'll be busy in the next hour? Remind her what an emergency constitutes and maybe delay going over to her if you know that you just saw her and she was taken care of.

Thank you so much for your caring heart and helpful advise.
So the boundaries idea is great but I tried it and gave up.
I think I maybe need some guidance in the boundaries to see if I did not set
a good set and should make a different set.

My mom cannot get up by herself (unless she sits and thinks about it a long time and stirs up the energy. She has Parkinsons, so if she does get the energy to start she will likely fall in the process. So she needs help with
most everything. We have a bell for her to ring for assistance.
My boundaries attempt said the bell was for emergencies only. I will come
in every hour on the hour and go over the list to make sure she has everything ok. Then leave and let her watch tv, sleep, whatever.
She said "OK" but did not do. She rings her bell to find out if any one is
here, if she wants a cracker, to tell me about the tv show, to ask what someone else is doing, get some tea, get a cookie, is there any chocolate....
She expects me to show up immediately. I think an emergency is if she
needs to go to the commode. The rest of the stuff should be on the hourly
care visit. I am afraid if I enforce the "boundary" she will get in some predicament and not ring. So do you have advise?

Carol, it seems like you know very well about caring for the elderly. The advice that you gave about researching the type of help for different needs is what got me thinking. It got me thinking of my uncle whom I wanted to place at a personal care service. The reason is because of how lonely he gets living alone.

This is a great article, it's very informative and helpful. I'm hoping to get someone to care of my mother, even if she moves in with us. I don't want her to be on her own, but even if she moves in, we have five kids that need our attention. We obviously want to help when we can, but it would be great to get someone to help us out.
