Using the Toilet!!!!!

GREAT NEWS! Griffin used the toilet again all by himself! He was in the bathtub and I had walked out of the bathroom just for a moment and heard the toilet seat clank open so I ran back into the bathroom and much to my surprise Griffin was standing there peeing in the toilet. I gave him all kinds of praise and he stood there when he was done just gleaming with pride. About half an hour later he had gone in the bathroom again and tore off his diaper and was attempting to go again but nothing would come out but I gave him tons of praise anyhow. I am so very proud of my little guy, he is really growing up. Yesterday morning Griffin had an eye doctor's appointment and it did not go well. He ended up having a meltdown because they made us wait so dang long plus they dialated his eyes which I think may have given him a headache. I asked if we could avoid doing the dialation but the woman told me how important it was for the doctor to see behind his eyes and check them out. I was worried about his sensory issues and the light hurting his eyes but I caved in and let her put the drops in. Griffin's meltdown lasted about 2 hours even after we finally got home he was still quite upset. Do any of you know if it was absolutely necessary for them to dialate his eyes or not?????? What do you think I should have done? What would you have done? He is a happy camper today and just got on the school bus really well, happy as can be!!!! Hope that you're having a great day!
