“…Studies on the benefits of owning and using the MCH handbook have been done many times, some of which are the studies on the users of services for infants and children, which lead to changes in the level of knowledge and self-confidence and ultimately improve the mothers' capacity to provide care at home. A study on the use of the MCH handbook for neonatal care users covers topics, such as early breastfeeding initiation, immediate breastfeeding, exclusive breastfeeding, and introduction to complementary food from breast milk, vitamin A intake, and the rate of morbidity and mortality among neonatal infants (Yanagisawa et al, 2015;Mori et al, 2015;Osaki et al, 2015;Osaki et al, 2019). Meanwhile, the studies on children focus on immunization visits, visits by health care providers in the event of specific conditions (Upper Respiratory Tract Infection (URTI), fever, and diarrhea), providing proper nourishment, consuming a variety of food, training children to eat on their own, monitoring the occurrence of underweight children and stunted growth, and delays in the child's cognitive growth (Usman, Akhtar, Habib, & Jehan, 2009;Usman et al, 2011;Dagvadorj, et al, 2017;Osaki et al, 2019).…”
