I took care of twins from time they were l until they were 4. They played on the floor right behind me--often with fabric scraps. I guess I was lucky because they entertained each other. I sewed at night when my kids were growing up. I worked away from home and after supper dishes were done, I sewed and the kids and their dad did whatever--usually watched TV. I remember the youngest boy spent one winter sitting on the corner of my sewing desk, watching me and playing with his tiny toy trucks. (It was a 5 ft oak office desk, sturdy as could be.)
