Kerta Village, Payangan Sub-district, is one of the regions in Gianyar Regency located in Bali with high stunting rate. Data obtained from village cadres and midwives through observations and short interviews, showed that in addition to stunting, several child health problems were also found such as lack of community knowledge on balanced nutrition, gadget addicts, exposure to cigarette smoking, and inappropriate parenting. Currently, Payangan Health Center which oversees the Kerta Payangan Village area has implemented various programs to support children's health, such as the mother and child health (KIA) program, one of which is manifested in the children's Integrated Healthcare Center services. In this village, a cadre of Toddler Family Development (BKB) was also formed and launched by the National Population and Family Planning Board (BKKBN). Although BKB cadres was formed in each Banjar, unfortunately it has not functioned optimally due to inadequate training related to children's health. Through this Community Service (PKM), BKB cadres were trained to design and manage a toddler mother class, which acts as a place for mothers to share and exchange health related experiences on toddler health. This research was carried out from August to September 2019 with a sample study of 37 participants from 8 Banjars in Kerta Village. The evaluated results showed that cadre knowledge on the toddler mother class increased after counseling. Participants are also trained to design it which is later applied independently in their respective work areas. Simulations and mentoring are conducted at the end of the activity to provide tangible experiences and increase participants' understanding. This activity is expected to increase the role of BKB cadres in improving toddlers health in Kerta Payangan Village, Gianyar.
