Homeschooling mommas!

If you have little kids that are not school aged yet, do they attend your lessons/routine with your old children? I will be homeschooling my elementary aged son starting next month but I also have a 2 year old. Should I include him in lessons and just make it “his level”, like if my eldest son is writing about Ocean animals, I give my 2 year old a picture of fish to color?

I am a certified teacher and taught for years but for various reasons will not be going back. But this is new territory for me!
