I used to attend the latin mass before I got married. Not exclusively, but most of the time. I've been married almost 6 years now and my first child is ready for kindergarden. My wife and I have attended the most conserative NO church in town. Sunday mass is somewhat reverent (at least father says a good mass). But I attended the 8th grade graduation mass last night and I was appaled. People were loud before mass, the 8th grade graudation girls looked like models on a runway. The school wins awards year after year. But I'm very concerned about the purity of my children. Also I'm concerned that the other parents and kids do not have my values. The pastor is good, but the kids could undermine everything. We have a latin parish 15 miles outside town. I'm thinking abut talking with my wife about sending our son there in a year. Eventually we'd have to sell our house in town and move to where the school is to make things easier.
My wife was not raised in the latin mass. I converted as a young adult pretty much right into the latin mass. My wife prays with me, and even prays the novus ordo divine office. My wife is modest, but doesn't wear the super long dresses and little house on the prairie garb. I think she is worried if we attend she'll have to have 10 kids and where burlap. (sorry for the exagerations). any suggestions on helping my wife to get on board here to start attending the latin mass some?
I will say that you are correct and right to be concerned about other kids undermining your children's values. That's the reason I pulled my kids from the NO school.
Have you considered homeschooling? I know that's not an option for everyone.
Also, 15 miles at my parish is considered a short, desirable drive.
There are lots of families that drive further than than for Sunday Mass and many of the families drive that far or slightly farther for school every day. It can be inconvenient, but sometimes moving is not an option. I would have had my boys in the school if I could find a drive that close. (We drive an hour each way for Mass - that is too far to go to school.) I would suggest putting him in school for to be sure you like it there (trad schools can also all be different and they can change depending on the priest) before moving. Moving is a long term situation that can make everyone miserable and unhappy as well. Be sure it's something you both want.
That prairie attire mentatlity may be in some really totally trad places, but it's the exception (the rare exception) at my chapel and not at all the rule. The little girls with lacy socks and black Mary Jane shoes may be wearing those, but the rest of us are in modest, knee length dresses and skirts.
I do know a few famiies with ten kids or more, but they don't seem to be unhappy about the situation - and none of them are wearing burlap.
(That was actually a really funny exaggeration!)
Once you get her there, if her experience is like most of the rest of us, she'll realize these things on her own.
