My sweet 5 year old has to wear glasses. She has a lazy eye(it is not that noticeable), and if it is not better in 3 months she will have to wear a patch over the "good" eye to strengthen the weak one. I had no idea she needed glasses, she seemed like she could see fine. In September 2008 I took all 3 of them because Hannah was complaining of headaches. She just needed reading glasses. Bryson's eyes were fine. They said Haley needed them then, but I wanted to get a second opinion, because she seemed fine. Now I feel really bad because we didn't go sooner. She wore her other ones, but they got broke when we were moving, so she has gone 4 months without them. Oh well you live in learn.
