My mum always told us to make sure to put her in a home, so that we could have a life. Mind you when the time came, she was OK for the 2 week respite care, thought it was a wee holiday. However, it became clear early on during her stay, that there was no way she could live on her own any more. She did become agitated for a while, made my brother & I feel guilty, but neither of us was prepared to take her in, especially with our own families. My brother & his wife both worked as did hubby & I, so no one could look after her as she'd often wander off. She was well looked after & began to really enjoy the company.
Of course all our mums are different & all our own circumstances are different too, but just thought I'd give you a small insight as to how it went with my mum.
