Best of Luck Nikki

Pam is directing a community-theatre play, and Dolly pressures her to cast Nikki in the lead although she failed the audition. A boy calls Avatar Nikki and Bobby's grandpa, so he attempts a youthful makeover. Sunny does a school report on a neighbor with a fantastic job and makes Rohan pose as the person for extra credit.

Himani throws a party to entertain Nikki and Bobby, dressing in a kangaroo costume with a pouch for her two youngest children. Avatar puts a cape on over his work clothes and calls himself Super Bijlee Man, but Himani disapproves of his meager efforts. Meanwhile, Sunny is deceived by Roli Aunty into attending a ceremony in honor of her charitable work.

Sunny is just gaining popularity when Himani gets a part-time nursing job at his school. They agree to pretend not to know each other, and she uses her maiden name, Batra. Meanwhile, Rohan has to babysit Nikki and Bobby, and begins a babysitting service with Popi.

Ayaan goes to apologize after getting into an argument with Dolly, but instead gets advice from Avatar on how to handle a Singh woman as a "Ladkiology expert". Himani overhears and instructs Dolly how to handle the situation. In the end, Ayaan apologizes. Meanwhile, Sunny avoids chores by spending the weekend with his friend Shibu at Rohan's apartment.

Dolly's team is on a losing streak, so new team mom, Himani, hosts a team-bonding slumber party in the hopes that they will work together to win a game. Meanwhile, Sunny starts dating a new girl, Saniya; Avatar immediately becomes annoyed by her father because he is clingy and has horrible manners.

Himani returns to work at the end of her maternity leave and finds her boss is divorced and working as well. Himani has hallucinations of Nikki and Bobby. Sunny and Rohan watch over Nikki but she runs away. Meanwhile, Dolly attends the mock parliamentary session alongside Ravi; Bobby nearly causes them to lose due to his frequent crying, but they soothe him by singing their final presentation, which leads them to victory. Himani decides to become a stay-at-home mom, and Avatar child-proofs all the locks so Nikki cannot run away.

Sunny tricks Himani into building a model rocket for his science class. Avatar enjoys peaceful quiet at Rohan's apartment since the Singh household has recently become loud and annoying.

Rohan announces that he is moving into an apartment with Popi to be closer to college; Himani is heartbroken and not ready for such a big change. Meanwhile, Sunny discovers that Avatar is afraid of carrying Bobby up and down the staircase after he dropped Nikki years ago.

Sunny begins to like a girl at school and tries to convince her that he has a soft side. At the park, Rohan and Popi decide to have another baby race, this time using tricycles.

The family takes a vacation to a haveli (English: historical mansion), and quickly becomes convinced that it is haunted. It turns out that they are on a prank TV show. Dolly pretends to be sick and throws a house party while the rest of the family is gone. Roli Aunty blows their cover, so they make a deal, but her parents eventually find out.

Avatar's aunt visits to help with Bobby, but drives Himani so crazy that she asks Dolly to keep the woman away. In a box of old things Roli Aunty gave them, Sunny and Rohan find an unmailed letter claiming money is buried in her backyard. They dig at the exact location mentioned, unwittingly excavating for her new hot tub. To pay her back they put green dye in the hot tub.

Nikki's birthday invitations may not have been mailed, and so Sunny and Rohan dress up as princesses in order to entertain her. Himani goes into labour and they hitchhike to the hospital on an ice-cream truck. On the way, Himani gives birth to their baby boy, Bobby Singh.

The baby is one week overdue, upsetting Himani's mood. Dolly tries to help her by inducing labor, but Himani does not want the new child to be born on Nikki's birthday and overshadow her. Avatar, Sunny, and Rohan shop for a new family car, but their purchase does not fit inside the garage. Sunny is sent to buy Nikki a doll for her birthday but forgets.

Himani and Avtaar vote on baby names for the fifth Singh child. Dolly is eager to find a quiet place to study for her final exam. The parents overhear Sunny expressing anxiety about being forgotten when new baby is born, and try to make up for lost time that they did not spend with Sunny.

Himani overhears through the baby monitor that Dolly and Ayann have been secretly rehearing the play Dinku the Donkey!. Dolly got the lead role and did not want Himani to steal the spotlight. In the end, Himani stands in for a cast member who broke a leg. Meanwhile, Avatar desperately wants to fix a fuse in a gorilla cage to prove to Sunny that he's cool.

Dolly makes an excuse to go to a graduation party with Ayaan. Rohan asks the flower-delivery girl to be his date, and she invites him to her graduation party--which is at her parents' house as she is learning through correspondence; Avatar goes to the doctor for a check-up and overhears the doctor speaking about another patient named Singh.

Himani convinces Pam's mom to throw her a baby shower, but the shower takes an unexpected twist when Nikki blurts out all the horrible things Himani said about her guests, making them angrily leave. Rohan and Sunny compete to go to a cricket match with Avatar.

The basketball team blame their losing streak on Dolly and Ayaan's relationship, so they fake a breakup in hopes the team will relax. Sunny starts acting on his best behaviour when he thinks his parents are considering sending him to a boarding school, a misunderstanding they do nothing to clear up.

With a fifth Singh child on the way, Himani demands a larger house. Dolly and Ayaan audition for "Romeo and Juliet" at their college; Ayaan gets the lead opposite a school trustee's daughter who has a crush on him. Sunny and Roli Aunty pull an escalating series of pranks to see who gets the last laugh. When the family is almost done packing, Himani reminisces and tells Avatar that she wants the family to stay in their home.

A psychic tells Dolly that she will become a film star during her family's vacation and she starts to believe it. Himani and Avatar discover that they were never officially married (the judge was a fraud), but Avatar doesn't want to abandon their planned ski holiday to correct the mistake. Rohan tumbles down a hill to a cabin with two beautiful teenage girls, which seems like heaven until their seven-foot dad arrives.

When she learns that Ritesh has a new girlfriend, Sheena, Dolly says she is also dating but is caught out. Rohan and Popi add a third member to their band; when Nikki gets him sick, Avatar steps in to perform but takes his role too far.

Recovering from her breakup, Dolly befriends Maya, and with Pam they make a music video about Ritesh, but when he stops by to apologize, Dolly decides to not upload it. Rohan and Sunny clash over sharing a room, and Sunny decides to sneak into the room Roli Aunty has kept for her son. Himani joins a gym with free babysitting but spends her time at a spa.

Dolly flatters Himani as a "cool mom" so she can attend a midnight movie with Pam, but she pocket-dials Himani, who overhears that it was an act. Himani and Pam's mom get revenge by publicly embarrassing the girls. Rohan pocket-dials his intimidating lab partner Sandy, who overhears how stupid Rohan thinks he is. Sunny and Avatar assemble Sunny's new toy helicopter while Sunny is driven crazy by Nikki's new toy "Bak Bak Bandar".

Sunny tricks Rohan into an unfavorable contract for money to buy an old used car. To teach him a lesson, Himani, Avatar, and Rohan try to convince him that the car is haunted.

Dolly becomes the new spokesmodel for Kukkad Nukkad, which seems like the perfect job until she realizes how much Rohan wanted the role. Avatar endeavors to capture a mouse and Sunny tries to prank him. Himani takes Nikki to a Music and Me class and gets over-competitive with another mother.

After agreeing to do a routine for the community talent show, Ritesh sees how bad a dancer Dolly is and fakes an injury. Popi abandons a ventriloquist act with Rohan to partner with Dolly, resulting in chaos at the show. Guri convinces Sunny she wants to help him run for class monitor, but instead smears him to bolster her own campaign.

Rohan makes a viral video of Nikki farting which attracts the local news where Himani seizes the spotlight and Avatar tries to promote his business. Dolly meets Ritesh's parents and loves their tidy, quiet house, while in contrast they see the chaotic Farty Nikki newscast.

The kids throw a surprise anniversary dinner for their parents, but Nikki loses her blanket and won't stop crying. Chaos ensues as Rohan gets locked out of the house with Nikki inside. Meanwhile, Sunny takes Avatar and Himani to the movies, but Himani gets stuck watching "Robot No. 1", a movie she hates.

Dolly tries to impress her Hindi teacher by bringing Nikki to class in costumes for a presentation, but Nikki vomits on the teacher and makes the class sick as well. Himani stands in for Avatar as Sunny's football coach, and they win their first game ever; the team hires her but her "have fun" approach doesn't work as well the next game. Meanwhile, Rohan takes Nikki to Nani ghar[HOME] and bonds with the Nani moms.

Dolly cat-sits for Roli Aunty, whose sister enlists a cat therapist to cheer up the pet. Sunny tells a girl he likes that he's an only child living with his single mother (to have things in common with her) and enlists Dolly to help him maintain the facade when she shows up at their busy home.

Avatar used to date Richa's mom, which causes trouble with Himani. Dolly tries to help Sunny with a school bully, Guri, who is actually a girl with a crush on him.

Dolly asks Ritesh to the school dance on a double date with Pam and Popi. The boys start a "dance-off" over Dolly, but end up bonding, leaving Dolly feeling left out. Sunny tries to get Himani and Avatar to fight at his PTA meeting to maintain his excuse for not doing homework.

Dolly is annoyed that her best friend Pam has become “texting buddies” with Himani, so she attempts to bond with Pam’s boring mother. Sunny and Rohan mistakenly believe that Roli aunty has killed her husband, so they go to Roli aunty's house to investigate.

Roli Aunty agrees to bring her dog inside if Avatar cuts down a tree, but Dolly and Rohan stage a sit-in to save their childhood tree-house. Avatar wages war against his disobedient kids while Himani gives them her support.

Himani pressures Dolly to be in the school play, "Dinku the Donkey", and she gets the part despite trying to blow the audition; a baby basketball match is set between Popi's nephew and Nikki.

Dolly encourages her parents to go out while the kids take care of the baby. Rohan flirts with a cute girl, Punam (Shivani Joshi), while minding Nikki--and accidentally brings the wrong baby home. After a failed search, the kids go to the restaurant to tell their parents--and find Nikki sitting with the cute girl's family a few tables over.

Dolly moves her study date with a cute boy, Ritesh, from the library to home because she has to help Avatar take care of Nikki while Himani returns to work. Avatar injures himself falling down the stairs, so Rohan must take him to the hospital where Himani works, leaving Dolly to watch Nikki.
