re: Toddlers revealing Past Lives

my son is 3 years old. I had something similar happen a few weeks ago. My son is named after his great grandfathers Henry (my side) and William (wife's side), but he goes by Hank which is what my grandfather went by. We were just talking before dinner and I asked him what his full name is and and he said Henry William Perrydawg. Then he looked me straight in the face and said I like that name, I hated Ebreska (which was my grandfathers middle name). Freaked me out a little because I do not ever recall telling him my grandfathers full name or if he has ever seen a picture of him, but my parents might have at some point. Then again my grandfather and I were thick as thieves growing up before he passed away. So maybe I got my best buddy back and we just reversed the roles.
