My oldest child is four, and I had not planned on starting home schooling until next fall when he will be five. However, he's been so interested in learning his letters that I've started having a casual school time with him in the mornings. The letter "E" has been his favorite so far - he was so excited about "envelope" having three of them! We're taking our time and I'm not pushing him too hard to be super accurate in his writing yet; mainly we are having fun and learning to sing the ABC song at the very least! After we've worked on a page or two in his workbook, I give him a @crayola Batman coloring page - so exciting for him!
