My two sleep at night. We go to bed about 10 pm, Serendipity is the first one out. Sometimes I'll be on the computer and Allie, the baby, doesn't lay down until I do. She's afraid I might get up and go to the bathroom without her I think. The apron strings are very short with this one and I don't think they will ever be cut.
Once I lay down she lays down next to me and they both stay in bed all night EXCEPT once in a blue moon Allie will get up and climb up my clothes to the top shelf of the closet and knock things around until I get up, get the step stool, bring Baster down under protest and put her back in bed with me. It's the only time she gets more than 3 ft away from. Not sure, but I suspect when she does that she's heard a mouse in the attack.
For those that haven't seen an explanation of my baby's name, It's Alabaster. She is all white, Persian. I call her Allie but when she's in trouble I call her Baster.
