Mine went to preschool even though I wanted to homeschool. I had different reasons for sending each child to a preschool.
I didn't see it as a daycare. I saw it as a chance for them to get out of the house and enjoy something a few hours a week and I worked from home while they each attended preschool so I didn't get any "fun" out of that free time, lol.
I also sent my kids to a private school for almost 2 years but have homeschooled the rest of the time other than that brief period in school. I have nothing against schools in general and never say never because I may have to use one again one day.
I'm also very committed to homeschooling right now in the present.
