For Children of All Ages is the third and final album by the American psychedelic rock band the Peanut Butter Conspiracy (PBC), and was released on Challenge Records, in 1969 (see 1969 in music).

Producer Dave Burgess was impressed by the resulting recordings, and encouraged more polished works, by instituting an eight-track and increasing the projects budget.

A revamped lineup included former Clear Light members, organist Ralph Schuckett, and drummer Michael Ney.

The album was the first and only release by the band to not credit vocalist Barbara Robison as "Sandi Peanut Butter", but rather by her actual name.

The PBC toured into 1970, however, thorough a combination of changing musical tastes and personnel indifferences, the group could not expand beyond their following in Los Angeles and disbanded in 1970.
