After all, Tadpoles is for dads. To give them the option of not attending violates the primary goal of the program. Furthermore, because of the age of the children, plenty of adult involvement is needed. Assign children without attending fathers to various dads in the group. A dad should supervise every child.
Some dads can handle two or three children.
Recruit other men in the church to be adult partners for those children whose dads cannot be there. College students or grandfathers are good choices, too. Work hard to get at least a core group of dads involved in Tadpoles. Encourage them to include some children from single-parent homes. Always keep the door open for every dad to participate.
