T he period of children under five years is the most important period in childdevelopment because the basic growth and development that occurs in toddlerhood willhave an impact and ignite every subsequent child's development. Growth anddevelopment is an irrational process that occurs with conception and continues intoadulthood. In addition to facing rapid physical growth, the development of brain poweris also important for the learning process and enrichment in the development ofintelligence, motor skills, speech and language, as well as social and independence.METHODSThis research is an analytic observational study with a cross-sectional design,conducted on 122 respondents aged 1-2 years. The variables obtained were nutritionalstatus and head circumference with gross motor development using KPSP. Dataanalysis was performed using the Fischer test with a significance level of p<0.05.RESULTThere were 122 respondents where nutritional status was dominated by normalnutrition (69,7%), head circumference was dominated by normocephaly (95,1%) andgross motor skills were dominated by appropriate (94.3%) Fischer test found that therewas a significant relationship between nutritional status with gross motor skills(p=0,00) and there was no significant relationship between nutritional status and headcircumference (p=0,528).CONCLUSIONIn this study, it was found that there was a significant relationship between nutritionalstatus and gross motor development in children aged 1-2 years. In this study, there wasno significant relationship between nutritional status and head circumference intoddlers aged 1-2 years
