There are a number of different ministries operating for children and families in the Diocese of New Westminster; and you can find information about all of them on this page.
There are many curricula available for Children's Ministry (ages 0-12), here are some that are widely used in this Diocese and the Anglican Church of Canada.
The single most influential factor in children becoming Christian adults is the presence of faith formation at home. It doesn't have to be difficult and parents don't need to have all the answers or be Sunday School teachers. These resources compile faith at home practices for families with children of all ages including: prayer and worship, bible and book studies, service ideas, crafts/activities and parenting resources. If you are interested in apps for prayer, see here. If you love podcasts, here is a list for Christian formation.
