I'm one of the 40+++ mother's here.
We got our first yorkie 16 years ago & after two sleepless nights, Mocha joined us in bed for the next 15 1/2 years!! I have to tell you I missed that little warm body at our feet when we lost her last May. We have had Kodah now for 3 weeks & I just always thought we would put her in bed with us, but when we went to pick her up & saw how tiny she was it scared me that we would smash her or she would fall off of the bed. So I got our hamper basket, lined it with a soft blanket & put her little bed down in the basket by my side of the bed. She has slept there without even a peep (except when she needs to go out). She does look up & makes sure she sees me before the lights go out! Occassionally, I hang over the side of my bed & pet her little belly when I know she's not sleeping & sure enough that usually knocks her back out!!
