Hello Baby

Hello Baby's first season premiered on June 23, 2009. With 9 members, Girls' Generation became mothers to a nine-month old boy named Cho Kyungsan.[3] In the first episode, the members are given pointers about child care before they meet the baby. Each episode, guest fathers come on the show to help. At the end of the day, the dads pick 'best mom' who is given certain privileges and a 'worst mom' who is given some punishment, usually clean-up duties. They also occasionally play games and other activities. Girls' Generation's season was well-received, and its 5th episode ranked first among cable channels in its time slot.[4] The show won 'Best Picture for Variety' at the 4th Korean Cable TV Awards in 2009.[5] It ended with a total of 22 episodes on November 17, 2009.

The second season started on January 19, 2010, and it features the boy band, SHINee, who have to take care of a 4-year-old toddler named Jung Yoo-geun. Like its previous season, the members have to deal with daily problems with having a child, such as preparing his meals, calming him down when he cries and doing other activities such as playing with him or teaching him new words. Because the members are not always with the child, they frequently sent him videos when they are away. In the final episode, Yoo-geun is given a time capsule by his 'fathers' which he would open when he turns 21.[6] The season ended on April 6, 2010, with 12 episodes and a special episode.[7][8]

The third season, featuring girl group T-ara, started on November 16, 2010. For several months, the group act as mothers to three young brothers named Moon Mason, Moon Mavin and Moon Maden.

The fourth season started on September 2, 2011. It portrays the four Sistar members (Hyolyn, Bora, Soyou and Dasom) acting as mothers and Super Junior's Leeteuk as a father taking care of a baby named Kim Kyumin (Hangul: 김규민). The season finished broadcasting on November 18, 2011.

This season is similar to that of Leeteuk's Find Mom project. It shows the process of finding the favorite mom amongst the four Sistar members. Unlike the past seasons, it was the baby who was leading the shows, not the parents.[9]

The fifth season stars boy band MBLAQ as fathers of three multi-cultural children: Dayoung (Vietnamese-Korean), Lauren (Korean-Canadian) and Leo (French-Korean).[10] The season began airing on January 19, 2012 and ended on April 5, 2012 with a total of 12 episodes. Like other seasons of Hello Baby, MBLAQ had to fulfill the task as parents to meet the needs of their kids.

The sixth season features boy band B1A4 as fathers to a couple of countryside kids, Eunsol and Hyunwoo. The concept of this season is getting to know Seoul, since all the members of the band came from the countryside as well.[11]

This season not only follows the established format of the care and growth of the children, but also unveils the members' journey into Seoul, since none of the members are from Seoul, as well as the children, who are not from Seoul either.

The seventh season, starring Boyfriend, started on January 4, 2013.[1] In this season, Boyfriend are fathers to two young toddlers.
