While the need for sleep may be related to giftedness, it could also be related to genetics. My DD3, who I believe is gifted, needs 12 hours a day (she got it from me since I need at least 10 or I lose it). She still takes a 3 hour nap and 9 hours at night everyday. My cousin, who is PG, and pursuing his PhD, always slept for 12+hours a day. I remember it because the adults in his life were always unhappy about how much he slept but boy, did he accomplish more than anyone else during the time he was awake
