I wouldn't worry about the fact that your child is so young-- in another 4 yrs it'll be time for kindergarten already! Time goes by faster than the speed of science! I would think that homeschoolers would be welcoming and helpful to the degree feasible. I would just state the matter plainly, for example, "my child is only 9 months old but how time flies, would love to start thinking about options and whatever elese I should be thinking about for homeschooling." etc.

It never hurts to ask. Many doors may open for you!

And if anyone's a jerk, well, better to find it out now rather than later.

Hope this helps.
