Aaron walked around the area the heart was in for awhile. He would drift away only to come back to it again and again, holding his ears each time. Eventually he said that he wanted to go in it in a very hesitant voice. Julia was there at the time, and she quickly spoke up, "I'll go in with you, Aaron. It's really not that bad."
After the first section of the heart, the kids came through a part where we could see them for a moment. Aaron's hands were firmly clenched over his ears, but Julia was slowly walking behind him, murmuring all the while, "It's okay, Aaron, it's okay, that was the only loud part, it gets a lot better after that." It felt like forever while we waited to see them again. I was so close to walking in the exit, expecting to find him frozen inside there, when the two of them walked out, together.
I know most of the Franklin Institute is still really tough for Aaron, but on Monday, he conquered his fear of the heart.
