Sorry for rubbish title but I'm not sure what I'm looking for.
My elderly Dad is going to be bedbound for a couple of months (hopefully no longer) and I'm looking for a way he can contact my deaf mum (while she's in the house) if he needs help or wants something.
A mobile would be the obvious thing but he hasn't got one and she always bloody leaves hers in another room so can't hear it!
Im not sure she would hear a bell or buzzer either - recommendations for decent hearing aids that don't cause itchy ears would also be appreciated.)
As well as driving me mad, I'm also worried about them both.
any ideas would be gratefully received!
