As a firm believer in exposing children to the faith in all its glory, without watering-down or simplifying the message "because they're children," the following article caught my eye:
Helping Children Enter into the Traditional Latin Mass
We do not attend Mass in the Extraordinary Form. My husband and I are interested, but it has simply not happened, yet.
The author of the article mentions the importance of "remote preparation" in readying your child to attend Mass in the EF. His suggestions seem familiar, very much like Creating a Catholic Culture in Your Home. In fact, the article seems to suggest that it's primarily in building the foundations at home that will inspire well-behaved children at Mass, particularly in the EF. Not a surprise!
