Adorable! The ABC song is one that can be learned early, so go for it.

I think your presence is the greatest gift you can give to a child. We have three kids in our lives: 5, 7, and 10, and when school was cancelled this year we homeschooled them. Er essentially, it was "unschooling"—no math, or reading/writing curriculum. Instead, we offered experiences. Most days, we started with a fire in the woods, with songs and prayers. Then we let the kids direct us on where they wished to be guided: art, exercise... It turned into a "school" of body, heart, mind, soul, and spirit. Definitely aligns with our higher calling in life, so we're planning to keep the ball rolling even when the public education gets kicking.
