Consider using a drive up parking lot registration system as an option for classes that involve parents with young children. Show families you care by eliminating the need for parents to get young children in and out of car seats and strollers - dodge cars in the parking lot - then stand in lines - fill in forms - all while juggling the little ones and keeping an eye on toddlers. Registration could take place in the comfort of their vehicle while the children are safely buckled in their seats. With a little planning, some clipboards and volunteers for traffic flow this might fit your ministry to young families.
