Hi Em, I had it turned right up, and I placed her end behind the head of her bed. I could actually hear her breathing. When she got out of bed, the sheets would rustle, that seemed to wake me. I think I got tuned in pretty quick, like when you've got a baby. It helped us a lot. We also had those plug in night lights set dawn to dusk, the one in Mum's room I plugged in at the bottom of her bed so it just glowed without being too bright in her face. That meant she was never in the dark so less likely to fall. We had them everywhere, right through the house to keep her safe. We still use them now, but they are mostly set to come on by movement, apart from the kitchen one which we leave on, we have a very senile cat of 20 who regularly falls off work tops if it's dark (but that's another story!) We also had a baby gate at the top of the stairs, had to put a padlock on it though as she learnt to open it after a while. We put the gate higher than you would for a baby, too low for her to get under but too high to climb over. That was our night safety routine, it worked for us. Love She. XX
