Here all this time I thought I was crazy for sewing early in the morning, and was wondering how many others do the same thing. Perhaps the treadle calms the baby down because of the rocking action it causes your body to make.
By the way, someone once told me that the times the baby is the most active before birth are the same times they will be most active after they are born.....3AM, huh?
Congrats on your impending arrival!
