I would guess at an average of 4 hours a day, 6 days a week. I care for an 18 mo GGS but he is one of the worlds best babies. He plays with his toys, entertains himself with singing and we dance to certain commercials. He still takes long naps2 1/2 to 3 1/2 hours. Today he is not feeling well, cutting stomach and eye teeth, so we are rocking and watching TV. I sit down to the computer several times through the day, but usually for short periods at a time.
