Best of Luck Nikki

Best of Luck Nikki is an Indian sitcom that originally aired on Disney Channel from 3 April 2011 to 16 April 2016. The series is the official Indian adaptation of the American series Good Luck Charlie, with a similar plot.
The adaptation was created by Phil Baker and Drew Vaupen, two of the creators of the original Good Luck Charlie, because they believed the series would be a great appeal to everyone in Indian households, not just children and teens. The episodes revolve around the Singh family as they adjust to the birth of their fourth child, Nikki. In each episode, Dolly Singh, the older sister, creates a video diary with advice for Nikki on navigating their family and life as a teenager.
The series revolves around a Punjabi family in Delhi called Singh who are adjusting to the birth of their fourth child Nikita, nicknamed Nikki. When parents Himani and Avatar Singh return to work, they ask their three older children Dolly, Rohan and Sunny to help raise their youngest sister. The events in each episode become material for a video diary series that Dolly creates, which she hopes will one day provide useful advice for Nikki. At the end of each video, Dolly says, "Best of luck, Nikki!".
Season 1 revolves around a studious Dolly and her crush on Ritesh, and she has adventures with her best friend Parminder, nicknamed Pam. Sunny frequently challenges the nosy neighbour Roli Aunty, while Rohan and his best friend Popi work on their band and try to impress girls. Himani has just returned to work after a maternity break, and Avatar is busy with his electronics business.
Season 2 shows Dolly dating her childhood nemesis Rahul, and Pam starts dating Rahul's best friend Jatin. Sunny has also started dating and tries to impress some of his classmates while maintaining his constant pranks. Rohan and Popi prepare to begin college, while Himani and Avatar struggle with a growing Nikki and their work.
Season 3 follows all of the children who have now grown up, and Himani who is pregnant again with a boy, whom they later name Bobby. Avatar is busy with work, while Sunny still indulges in pranks and experiences typical high-school problems. Dolly is now dating the basketball captain Ayaan, and Rohan experiments with his career choices at college. Nikki enrolls in a playschool, and they all help with raising Bobby. As the season's end, Avatar mistakenly frees an exotic termite that destroys the family home, forcing the Singhs to move.
Season 4 is the final of the series and was released after a long wait. All the characters had aged and Himani became pregnant again. Avatar struggles to arrange their older house and keeps the family in a one-room flat while waiting. Rohan and Popi move to their own flat. Rohan has entered culinary school, while Dolly begins interning with her father and pursues journalism. She starts dating her father's assistant Avishkaar, while Sunny starts dating Roli Aunty's granddaughter Riya.
The series ends with Rohan operating a food truck in partnership with Avatar, Dolly moving to Mumbai for studies, Bobby becoming the next chhota shaitan (devil child), Nikki finally accepting Bobby and Kritika as her siblings and Himani delivering her last and sixth child in addition to her work as host at her news company. Dolly's last video diary is completed and Nikki is set to follow in Dolly's footsteps by recording video diaries for Kookie (Kritika).
