Parents are the first teachers. I taught my children to read before they entered school at 3 years old in my country. In the US it’s older but I still make sure they can read before entering school. You forgot the fun. I make learning fun and they wanted the fun so they learn. Lol. I had a great time too and I do it straight up to high school. Yes, I would do it again. I love working with children, I learn so much. Parents are the first teachers. (I had to repeat that)
