My sister has a young baby and has recently returned to work full time. She has arranged to have a childminder 3 days per week and for the other 2 days she has asked our elderly mother (mid 70s) to make a 4 hour round trip on a train alone and stay overnight to look after the baby while she's at work.
I have a number of issues with this. I think it is too much to expect of someone our mother's age and I don't like the thought of her travelling to and from London on her own. I am also concerned that our father is too vulnerable to be left on his own. He has a number of health problems which he has to be reminded to take medication for and has dementia. He struggles to get in and out of the bed on his own and I worry about the possibility of him having a fall and nobody being there to help him.
Would I be unreasonable to raise my concerns or do I stay out of it? It annoys me that all of this is for financial reasons (so sis doesn't have to pay for a childminder 5 days a week) and is to the detriment of both our parents.
