There are sexual references that kids will most likely overlook. In one episode, Leo says Max is changing(thinking of his mother before himself) and Max says these may be the changes the gym teacher mentioned in Health class(referring to puberty/sexual changes.) In another, Sydney tells Leo's son that he does not want to see the town's Naked Bikers race. Olive shakes her head in fear and agreement.
In "Crush Hour", Sydney has a crush on Jake.
"Girlz II Women" explains about periods that females have. Max says that he finds that comment "Sexist".
Little innuendos happen.
one episode revolves around periods
