We officially began homeschooling our oldest sons (ages 4 and 6) this week.
Our preschooler has been miserable for months, crying every morning and not wanting to attend preschool. I think the 5 mornings a week format was too much for him.
As for our first grader, he is hyperactive and impulsive (read: ADHD) and was having so much trouble sitting still, keeping his hands to himself, and fighting his urges to grab, play, & wrestle with other boys in the hallways and lines. Read: trouble being a very active boy in school, where that is not tolerated. After a few detentions and even a suspension, the principal was suggesting medication (read: Brain drugs like Ritalin). It just wasn't the best situation for him to be in, and we will not medicate our outgoing, friendly, sociable, active 6-year old.
Another plus for our family to homeschool is my husband's work schedule. Have I mentioned that he works 2nd shift? That means he is gone from 3 pm until about 1:30 am (with his commute). And he sleeps until 8 am or so. This means when the kids are in school they don't see their father until the weekend. During the school week, I was single-parenting. I was growing very resentful, as you can imagine.
Homeschooling definitely fits our family situation much better, and so far everyone seems much happier. That's so important, after all. Everyon'e happiness.
