It just dawned on me that I have been following Naruto for years now but I have never asked and no fan I know of has ever asked me about naruto's foster family. So who looked after naruto as a child and why does naruto never talk of his foster family if there ever was one?
well ... I understand Kishi specifically wanted it this way as it is important for the character's development so we understand him and why he is the way he is but it does also show that Konoha is a one messed up village to allow an infant to live alone with no adult supervision.
My answer is
implied in my reply...nobody would be willing to
take care of what they think is a monster unless
it is ordered by Sarutobi Hiruzen. Assuming there
is someone who took care of Naruto for a long
time, it is also possible that he/she is killed
during a mission which then leave Naruto living
alone and does things to gain attention during his
childhood. That "foster parent" could
have died at the age when it is not remembered for
long(in reality, most people remember memories
from as early as 6 years old but some people can
even remember events from as early as 4 years
