Rushil's reincarnation

Rushil uses the term "reborn" as part of his daily vocabulary. Just today he was telling his father how it was ok that he didn't participate in the swimming races at school because he can always participate in his next life. A few weeks ago, he was lying in bed and was really concerned about being reborn into another family and that as a baby he would have to get vaccinated again and he really didn't want to go through all that. He was actually so worried about it that he could not sleep until I comforted him. I guess rebirth is a way he copes with death.
