Where in Kenya did Obama spend his childhood?

Nowhere. The president was born in Honolulu in 1961, and spent his first five years there. He spent four years in Indonesia with his mom and step-father, and then moved back to Hawaii for the rest of his youth. But if you are talking about the president's biological father, who has the same name as the president, he was indeed from Kenya, and came to Hawaii to study. He ultimately went back to Kenya, and died in Nairobi in 1982. But there is no evidence the president ever visited Kenya until the late 1980s.
