Hubs bought a new bed frame last week and it's been a week of better sleep for us. It was especially wonderful for me to be able to get up while Yamee's sleeping, to pee or cuddle up with Yakee in his bed, without the bed creaking and rocking which wakes Yamee up.
Now, our mattress lies firm and flat, just like Yakee's.
Sometimes, the sleep gets so good though that I don't wake up to Yamee's whimpering. Hehe.
