My husbands family has a history of depression. His sister has had two out of three children on prozac. I know one was four and the other might of been 3. I don't know how people(doctor) can know for sure that these children were depressed and in need of this drug. I think it's horrible and finally spoke up the second time(I don't know if it did any good). It's a matter of time before the third child gets her prozac.
