S3E21 Whoa, Baby!

Caitlin develops a crush on Sawyer, but worries that her smaller chest won't attract him since he prefers girls with larger breasts. In an attempt to impress him, she purchases a water bra, which inspires Jonesy to create a line of bras filled with water balloons. Meanwhile, Diego and Robbie drive Jen up the wall, as she can’t stand her three stepbrothers. On top of that, she learns her mom is expecting another child and becomes anxious to find out whether it will be a boy or a girl.
