Awesome decsion to make and so early I wish I had gotten started earlier too. My daughter is 4 and I feel a little pressure to get things going. God bless!
I decided to homeschool when my oldest was 2 also, about 4 years ago. I bought tons of homeschooling books and read them straight through, and I'm so glad I did! I immediately lent them to my sister, whose oldest was then 5 and in Kindergarten. My sister was very unhappy with the school, which was supposed to have one of the best public school programs in California. Within 2 weeks of reading those books, she pulled out her daughter and has never looked back. It's great, because now I have a sister homeschooling 3 kids that I can turn to when I need experienced advice.
