We found out at Liam's eye doctor appointment last week that we need to start patching him again. Two hours a day. I was a little nervous about it. We haven't had to patch since he was two. But we started today and he did great. I've got fun patches for him to pick from, and he picked a couple M&M's as a reward when his time was up. It helps that he can tell time. He can look at the clock and know how much time is left. What a little trooper!
