I look after my mum 6 days a week and my sister has her of a night, when my sister has her she sleeps great, yet when I have her 2 nights a week she won't sleep at all. It's not as if she doesn't see me to not be comfortable... does anyone else have this problem?
Could you clarify who looks after your mom, when? You do 6 days and sister does 1 day? You have her 2 nights and sister has her 5 nights? Or is someone else involved also?
And CM's question is relevant. Where is the care given -- in mom's place or in your homes?
You'll get more specific answers by providing a little more information.
