Sophie started sleeping with us when she was well over a year old. I wanted to be sure that she was well potty trained before I would let her be free in our bedroom while we were asleep
. By then she weighed about seven pounds, and we have had a stool for her to use to get up and down from the bed. We have noticed that she will sleep all night with us during the winter, but once the weather begins to get warmer, she will jump down and sleep on the floor for a time. Usually we find her in bed with us in the morning. She does very well in our bed.
