Can a POA sister restrict the family from visiting dying mother in my sister’s home?

You say you do not have information, but it appears that you do understand that your Sis is and has been caring for your dying Mom, and you understand that she is dying. There are six of you, and your Sis is dealing with the care of a dying person. In my opinion her requirements are entirely reasonable. You will undoubtedly do a lot better by offering meals, support, housekeeping, casseroles, love, and asking "What can we do for YOU". Animosity will get you shut out, imho. It is up to your the approach you take to your caregiver sister; the consequences will you yours as well. I am sorry you are facing this sad loss.

Yes she can.   I am sorry about your mom and the situation.

 BTW, did you guys help out POA sister at all?

Your sister is totally reasonable in her restrictions & allowance of the visits of her siblings. In caregiving there is usually a round the clock routine one has to make in caring for a loved one... not only that but caregiving in & of itself is highly stressful!
My mom has Dementia so it is very important to stick to routine, If not she can become agitated & unruly. My Mom’s Dr. ordered a nurse & therapists to come to our home 3-4 times a week, 1 hr for each...that was a total wipe out...
In caregiving I have become temperamental & moody.
My Sister told me I have a bad attitude, Smh. I told her until, she cares for Mom from the moment she opens her eyes in the morning to when she closes them for sleep at nights, (if she sleeps), she had no room to judge my temperament.
When ppl ‘step in’ that have not helped care for the LO it can offset the routine..even if on deathbed. There’s still care that needs to be had.
Abide by your sisters wishes.. she probably could’ve used the help to give herself a sanity break when your Mom wasn’t on her deathbed.
Sorry, but there may even be a bit of resentment from your caregiver sister but otherwise she’s being totally reasonable.
GodSpeed...

You say one visit per day per sibling, and there are 6 of you? That is alot of visits, but I understand you all want to see her. I agree with the advice to take some food, offer to help in some way. Your sister is probably stressed out too.

One visit per day per sibling is five visits to your sister's home per day. This is a lot during a huge Covid-19 spike while she is caring for someone full-time. I understand that you may want to stay in her house 24-hours a day to be close to your mother, but put yourself in your sister's place. Would you want 5 siblings underfoot constantly, criticizing every decision you've made in the last few months, demanding to be fed, probably reverting to their childish behavior, and expecting you to rise above it all, settle all disagreements, and grieve in a way that is above reproach. No? Then give her a break.

If it is one visit per day/per sibling, that is perfectly reasonable. That means that you each have to schedule a time with her to come see Mom, and Sis doesn't have to deal with all of you at once while trying to keep Mom calm and comfortable.

If she is saying only one visit per day, that is another matter and means that there is a possibility that some of you might not get to see Mom and tell her in person you love her before she passes.

Is this a new rule? Have you all been helping care for Mom and visiting all along?

Please try to empathize with Sis too. This is a tough job physically and emotionally. She may be trying her best or she may be showing resentment at carrying the full burden. Figure out which one and act appropriately. Sis will be here long after Mom is gone. We all should know how precious family relationships are and that they can be fragile in times of stress. We all make mistakes and misinterpret at times, so try to give Sis credit for care and be supportive.

This sounds reasonable. Caregiving for the dying is very high stress. I’m so sorry for your pain. However, please be supportive to your sister. I had to limit info to my dying dad’s siblings, because incorrect information would have been posted all over social media. I felt like I needed to protect my dad and myself from a potential circus. I pray you and your siblings have a meaningful goodbye time with your mom. This is such a hard time for your entire family.

My mom passed away last year and the only thing I would've done differently as POA would be to have been less generous with information and visits. It created the perfect opportunity for criticism (of me) and medical interference that caused my mom physical and mental pain and A LOT of emotional stress for me. My goal was to keep the channels of communication open, but it backfired. I rarely speak with sis now.

What support have you offered your sister? Caring for a dying parent is overwhelming.

I looked after my Mom for over 20 years without sibling help and as she came closer to her final days, she was so easily stressed out and exhausted by anything different in her schedule and would be agitated and not able to sleep after visits from family. I asked family to only visit for very short times and not at the same time to keep Mom calm. One per day would have been too much at that point. Family who are not caregivers are not usually proxy to all the needs of the dying parent. This could be a reason for you to consider. Why she is not allowing siblings to know her medical information is puzzling but has anyone asked her why? By the end of Mom's life I was exhausted in every way and unless you have been a 24/7 caretaker it is impossible to understand- be kind to her and ask questions to find out the "why's" is my suggestion. She has watched the decline and is mourning as she has watched day after day the slow loss of the parent's abilities etc., on top of her own total exhaustion. Be kind and compassionate to her as well as your parent.
