I'm new here, so forgive me if I misstep, but I didn't find any threads that talked about this question.
My oldest is a very verbal 3 1/2 yo, who seems to be teaching himself to read. Although it's hard to tell what is reading and what is memorizing with the usual books, tonight he finished a few of my sentences on a new-to-him library book this evening that I'm fairly certain he'd never seen before. I had been planning to start the OPGTR with him in January when he turns 4, but now I'm wondering if I should start earlier so that he learns correctly from the beginning? He knows all his letters and letter sounds, and is very reliable at distinguishing between his name and his brother's name wherever they are written. For what it's worth, he has a good attention span for his age (I think? he'll sit for 30-40 min while I read to him), and does a lot of "reading" on his own (instead of napping, sigh). Given that this is our first child, I'd really appreciate anyone who can share their advice or experiences, good or bad, with young readers.
