My children knew all my time was not devoted to all their attention demands. When playtime with them was over, it was over. I wanted them to learn how to entertain themselves and use their own imagination. From toddlers unrolling rolls of toilet paper in my sewing room while I sewed to pre school of making the world's longest line using yarn, they came up with some imaginative activities and didn't expect me to entertain them all day. I would have been frazzled if they clung to me all day long.
