MLS is Michigan Lutheran Seminary. It's one of two prep high schools that the WELS maintains.
My oldest, Jake, has been brought up in the word his entire life. When he was little, I read him bible stories that had pictures, when he got a little older I used Little Visits with God. Every night we said prayers and had devotions, and we went to church almost every Sunday. There was a time that I didn't take him to church when he was younger than two because he was a disruptive child and it made it so that I couldn't even get anything out of the service. Fortunately, we had a radio broadcast as well, so I was able to listen to that with Jake on the Sundays that we missed.
Jake has attended a Lutheran school since kindergarten, and will continue to attend one as long there is one available. He hopes to attend MLS for high school, provided we are still in the area but he is not sure if he wants to be a pastor or not. Hubby encourages him to think about, but he won't be forced into it or anything.
As for our two youngest, they participate in devotions at night, even if by just sitting in their cribs and listening. I read them bible stories like I did with their big brother, and we talk about Jesus a lot. Aaron, who will be two in February (I always jump the gun on ages) likes the story of Noah's Ark the best, because he can make the animal noises. David, who will be one in January, likes to fold his hands when we pray.
We just make sure that God is a part of our daily lives.
