I’ve taught all my kiddos to read. We don’t do sight words, but actual phonics. My 5 yo loves to use a magnadoodle, or I put rice in a pan for her and she draws things with her fingers. Having him color a picture every day really develops fine motor skills. You are more than capable of teaching him to read. Mine are 4th, 2nd, and kindergarten. It’s seems so scary at first. But I promise you will never regret it.
