If it is with a certified daycare, the men will need to get clearances just like the women that work there. When my son was about 3 years old, there was a man (student) that worked at his daycare. He loved him to pieces. Fast forward ....... I work at a center that has employed several men over the years. The after school boys like the activities they have planned, follow them around, these men may be the only normal men in their lives. Many have no dad at home or even in their lives. Or they have TOO many men that really do not interact with them on a good level. It did take some of the girls a bit longer to feel comfortable with the men, but eventually they too were engaged in learning activities.
