Hi and welcome! You actually welcomed me on my first ever post, too!
My husband was never really for homeschooling either. When we had our twin boys though, we couldn't afford preschool. I was actually sad for them to be missing out on all the fun activities, while their friends were all gone during the day. So I decided to do very light preschool at home: crafts, games, etc. By the end of the year my husband and I were both amazed at how much more they both learned compared to their same aged peers. They can swim, ride their bike without training wheels, started reading before kindergarten, and many more things. We still decided to go the public school route, but he is no longer opposed to homeschooling if this was my choice.
Did you ask your husband why he doesn't want you to homeschool? If this is really what you want, or feel is the best for your kids, maybe there is a solution to his concerns?
