Each family needs to decide what will work for them. IF Jenna had already decided to homeschool. Right now, she only seems to be considering it.

If she she pulls her out, and subsequently decides homeschooling won't work in their situation, she will have to put the little girl back in school.

The decision to homeschool is a big commitment, and it shouldn't be taken lightly. Each family needs to decide what will work for them.
