Attorneys,jointly and severally, I am confused

[Botticelli]

My Mother is drawing up an LPA, and us 3 daughters are named as attorneys,to act "jointly and severally." She is getting frail, and more confused,though ok at the moment.
How much should we consult when it comes to making decisions?
It seems that we could each make a decision and not tell the other attorneys, as long as we thought it was in Mums best interests. Is this correct, or are we obliged to notify the other attorneys of all decisions?
I ask because I live close to Mum, and my sisters live a way away, so its me who will be doing much of the day to day stuff, even though we all want to help, and we all love her, and want whats best for her.
And can one attorney override the other two? and what can you do if one attorney acts seperatly and does something that isn't agreed with one or both the others?
I'm sure I'm worrying needlessly, but I do want to think ahead, and I have seen families disagreeing about care etc. Who decides which is the right decision when there isn't agreement? Especially when all daughters think they know what Mum would want!

Jointly and severally makes sense other wise you would all have to act together for every trivial thing. You might find one of you is better placed to deal with certain things. Your mother can specify if there are particular things that you should agree on.
Have a look at this it's very helpful in explaining POA.
I have just set it up for my mother and it was quite straightforward.

Thanks v. much for that squirrel, it's nice to hear of others experiences. Yes, she could say we must all agree about any large purchases for example,or care decisions must be made together.

The reason that the LPA will have been drawn up with joint and several responsibility is so that, for example, say you are on holiday for three weeks in darkest Borneo, the other two attorneys can deal with paying your mum's gas bill without you having to sign the cheque.
