I am actually wondering how you got your son diagnosed so early? Was it really obvious? I am concerned for my son b/c I have a lazy eye. I have since been told that early diagnosis could have corrected for me as a child-either a patch or therapy. It's mild enough & only in one eye, so I can get away without wearing glasses (tho' I should) b/c my other eye is fine & compensates for the bad one. My pediatrician hasn't seemed concerned & my most recent eye doctor had told me (when I asked) that it was a little early to bring my son in. Hmmm....
Anyway, my son is VERY VERY ACTIVE & now that he's almost 2, I think it would still be a challenge to get him to wear glasses. He never liked sun glasses. Last summer when we were going to FL, I had to be more persistent than he was when it came to getting him to wear a hat. It also helped that daddy likes to wear a hat. We made it fun. This winter, my son has actually really gotten into wearing his hat, coat, and mittens. I think it's b/c I insisted-and insisted for awhile, but I also always wear my hat & gloves & point that out to him. Plus, if he gets his hat & coat on, we go OUTSIDE. Pretty positive. So maybe a doll or stuffed animal with glasses. Maybe Arthur books, since he wears glasses? I bet getting some "fake glasses" like the other person said would help too. Maybe you could just take the lenses out of some dollar store reading glasses. Oooh, Mr. Potato Head has glasses too. That could be fun. Oh I also saw that some kid's glasses have an elastic strap that goes around their heads. My son could get that off too, but it might be enough work that after awhile he'd give up? Good luck to you.
