Something that some might find interesting. All my kids were reading by age 5 except for my son.
It wasn't that he didn't have the ability, he just didn't want to. I had to convince him that reading was a "superpower" I would write simple notes to his older sister that she could read but he could not. He decided that he wanted to learn to read those notes and if I recall correctly it was like a month or two and he was reading them.
He recently turned 7 and last time we tested him he was reading at 5th grade level. My 5th grader is reading at 10th grade level. She also plays the recorder, piano and is learning guitar.
For anybody looking for homeschooling resources, we use: Acellus, Lotty Learns, Kahn Academy, and Kahn Academy kids (these are different) Kids type, and DannyGo for exercise.
