DS8 and DD5 taught themselves to read at ages 2 and 3. (We never read to them.) DD3 isn't showing any signs of reading yet, though she knows the alphabet. We sometimes see older siblings explaining schooly things to younger siblings, so maybe DD5 will teach DD3 to read as part of their playing. Has anyone had older siblings teaching younger siblings to read?
Yes. That's why my post mentions my oldest reading to my younger ones. #1 asked to be taught to read at 3, and was. #1 has gone on to do much more explicit instruction in phonemic awareness, word attack, and blending with the younger siblings than I had planned to do myself!
