Our ODS really loved books (looking at and being read to) until partway through his kindergarten year. He really wasn't too fond of being taught to read, and I found it a bit nerve wracking that I couldn't get it to "take". (He knew all his letters and could spell some words, go figure.) Seemingly overnight, reading started for him, and he took off like a rocket. He's seven and in second grade now, and rapidly burning through our large library's collection.

I would echo, though, the suggestion to have his eyes checked with an eye doctor used to checking children. DS is very farsighted and I think that also slowed his start with reading, as it was really a strain.
