According to KBS, the kids are still too young to appear on the show as fixed members, and therefore, the joint baby care segments of the show will be eliminated from the program. However, the families will still appear on the show from time to time individually. The show further explained, "In the case of infants, it's difficult to capture their growth every week. It's the same reason that Ki Tae Young and Rohee do not come out every week." 

Meanwhile, 'Superman is Back' also recently added former Sechskies member Ko Ji Yong and his son Seungjae to the show. Don't worry folks, we'll still see the O.G.G families occasionally!
