We have told Brody that he is a big brother, but that Caleb is very sick and in the hospital. Tim and I have decided that we will wait to introduce Brody and Caleb until things become more stable. The room is pretty scary for adults so we can't imagine what it would be like through the eyes of a five-year-old boy. We talk about Caleb and he asks to visit him, so hopefully, this can happen sooner than later!!!
