Jiraiya was busy keeping an eye on Orochimaru, and couldn't exactly take a baby with him. Kakashi was in the ANBU, a position where he easily could die. Neither were good candidates to take care of a baby.

Presumably, Hiruzen had some people take care of Naruto. If he wanted to avoid anyone getting attached, then he would rotate the caretakers frequently.
