Good Luck Charlie

The Duncans are separated on route to Amy’s (Leigh-Allyn Baker) parents in Palm Springs after Teddy (Bridgit Mendler) makes a snap decision to give up her airline seat for a free ticket. Unwilling to let her daughter travel alone, Amy also disembarks the plane only to discover the next flight to Palm Springs departs after Christmas, on December 26. Meanwhile, the rest of the family arrives in Palm Springs, but things aren’t any easier as Bob (Eric Allan Kramer) tries to care for Charlie (Mia Talerico) under the watchful eye of Amy’s mom Petunia (Debra Monk) who does not like Bob at all; PJ (Jason Dolley) learns the pros and cons of his grandparents’ pool after getting a sunburn, and Gabe (Bradley Steven Perry) quickly realizes the downfalls of teaching Grandpa Hank (Michael Kagan) how to play his video game and Grandpa becomes addicted. Meanwhile, Teddy finds out Amy is pregnant.

When Bob has an accident, the kids must take care of him and Charlie while avoiding their mother.

It's been a while since Amy and Bob have been on a date, so Teddy encourages them to go to dinner while the kids babysit Charlie. When PJ takes Charlie to the park, he accidentally swaps strollers and babies with a cute girl, Emma.

Gabe and PJ mistakenly believe something fishy is going on with their neighbor, Mrs. Dabney, so they investigate. Meanwhile, Teddy is annoyed that her best friend Ivy has become texting buddies with Amy.

Charlie turns 2 years old.

Bob confiscates Teddy's cell phone when she exceeds her texting limit. Bob demands that she must pay the bill; Teddy is forced to get a job at Otto's Grotto, dressed as an octopus. Her job is a complete nightmare when it comes to dealing with children who are out of control. Meanwhile, PJ uses Charlie as a girl magnet, but his plan backfires when his new girlfriend, Kayla (Skyler Day), only seems to be interested in Charlie rather than PJ. Elsewhere, Amy is obsessed with trying to beat Gabe at video game tennis.

Bob and Amy try to potty train Charlie but when she flushes her toys down the toilet, Bob must fix the plumbing. Unfortunately, Bob cracks a pipe and water sprays him and the nearby fuse box, resulting in a blackout. So, to finish their video game, PJ and Gabe run a cable from Mrs. Dabney's fuse box to power the TV set, eventually giving her house a blackout. Meanwhile, Teddy helps Ivy prepare for her first online chat with Raymond Blues (Daniel Curtis Lee), a guy she likes.

With the new baby coming, Amy decide the family needs to move to a new house. Teddy and Spencer audition for better acting reenactment roles at Super Adventureland. With Gabe leaving the neighborhood, he and Mrs. Dabney pull the ultimate pranks on each other.

Everyone at school thinks that Teddy is a jinx when Spencer's basketball team begins losing games. Overhearing that Amy and Bob are thinking about sending him to military school, Gabe starts acting in his best behavior. PJ frequently attends his local barbershop to spend time with an attractive female barber.

Amy convinces Mary Lou Wentz to throw her a baby shower, but the event turns bad when Charlie blurts out all the horrible things Amy said about her baby shower guests.

Starting from where the season 3 finale left off, the Duncans' house has been destroyed by termites and they must build a new one, with the help of The Muppets.

Teddy moves on and looks for a new guy who looks just like Spencer.

Gabe has a crush on Mrs. Dabney's granddaughter.
