"How can I keep the parents of children in my catechetical program from seeing the session time as 'drop off and pick up' child care? They do not get involved in our program at all."
Parents today are stressed and busy on so many levels, but we should be able to help them realize how important their children's faith formation is and invite them to be a partner. Try to coordinate with whomever is responsible for Adult Formation in your parish and offer some parenting programs, or perhaps a lectionary-based Scripture class during the time of children's classes. I would think you could start with one or two days a month ... not every week. If the programs are helpful to them, they will ask for more. Always be respectful of those parents who may not come to classes, but continue to invite them.
