Easy Reader, Is That His Name?

Seems like Superboy has known his letters and their sounds forever, but he wasn't much interested in using them for reading. He had great fun learning to write them, and we read together all the time, but the idea of reading himself just wasn't much of a draw. No worries; seriously, no reason to push that at his age, right? But lately his interest has been growing by leaps and bounds. Now he reads to little sister. Here they are looking at an "I Spy" book Grandpa S. gave to the Boy on his second birthday. What a lucky girl! She sure loves her big brother.
