I'll tell my story. Hopefully it may help you decide what to do.
I have five children myself, ranging from 11 years to 10 months.
I originally homeschooled my first, when she was in kindergarten. I had two small ones, and one was an infant at the time. I had gotten her into a charter school situation funded by the publik skoolz here, and they gave way too much work, and I think that's what turned me away from that. Way too much.
Then, I sent my eldest and my second oldest to a school that had half day kindergarten for my second, and that was a nice school and everything, but my car ended up breaking down and I couldn't take them, and there was no bus to pick them up. Also, I found out that the first grade teacher was pro-abortion (iirc) and I sent them to the school down the street.
Because, at that time, I didn't know my rights, I was coerced into vaccinating my children. I'd already vaccinated my first two but my son, I hadn't yet, and I was basically threatened if I didn't, so I did. (I think that may be why he has some problems now, but God allowed it for whatever reason, and I accept it.)
So he went to the same skool with them, publik, for one year.
I was absolutely disgusted with the way they were acting, and there was no way I was doing that again, so I homeschooled them all the year after that.
Surely it is a weakness in my temperament that I haven't sufficiently mastered, and I really didn't do that good of a job at homeschooling them, so I decided that I had to start looking elsewhere once again. I had them doing the time4learning program which is largely a computer based school program.
I'd been hearing about this one school that lost a bunch of students because they were forced to attend the Novus Ordo mess, and I wondered if there were a way I could send them without them being forced to participate. It was really expensive, but I worked out a deal with the principal over there, and this year I was able to send all three. My daughter who will be 6 this Sunday, didn't go to school this year, because the required age to be in school is 6, and I thought it would be nice if she stayed home with me another year. She's been a big help, too, with my infant son.
They are forced, (yes, it's a required "school function") to attend the Novus Ordo mess, but I hacked out a deal, that, yes, they would go with their class, but I would go also, and sit right behind them, as to make certain they were not forced to participate. I told them in no uncertain terms, that we neither go to the novus ordo, nor would we ever participate, because that is not how we worship, and not how we believe. So as long as they could just quietly sit there and read a book, or pray a rosary, and were not forced to participate, they could go to that school.
It's worked out nicely, although, we're called in a few times, to discuss the mass, and whatnot. The principal asked me if I were getting anything out of the mess during a phone call, and I told him, "No, sir, I'm being completely honest with you. I get nothing out of it. There is no joy in attending it, and I actually wish to be anywhere else but inside that church when that service is going on. But I tolerate it because I must."
I've had to explain to my children that they're not allowed to discuss the N.O. or the Mass at school because we didn't want any arguments in school or "taunting" or whatever. If I had my way, my children would be talking about the Mass and trying to convince their schoolmates to go to only that Mass, but my options were:
1) Homeschool with an infant
2) Publik Skool
3) This school
I don't know what my options are next year, as I don't know if the financial assistance that was there this year, will be there next year.
You are not alone. Every single family I know is in this predicament unless they live in Saint Mary's, and have a lot of money to shell out.
God Bless you, and I'll pray for you, and please recommend me to Our Lady, when you pray for me, if you do.
