English edition available from:  Amazon InterVarsity Press

This book has really helped us to think about how we can train our children to participate in the regular worship service of the church, and it gave me new motivation and new ideas for how to help our son to start to be more of a part of worship, instead of just playing with toys during the service.  There is also some helpful discussion about the pros and cons of children's church and if the kids do leave for part of the service, how that time apart for the kids can be used to help them to learn to worship in anticipation of integration with the regular church service.
