Meanwhile, Sherwood Schwartz could find six good to very good child actors specifying three blonde girls (the youngest one in curls) and three brunet boys (Bobby dyed his, but close enough).

Brandon Cruz in "The Courtship of Eddie's Father" was over the top cloying. And Hal, Butch, and Prudence undermined the excellent acting of Juliet Mills and Richard Long in Nanny and the Professor.
