The first years of life are fundamental to the acquisition of motor, cognitive, and social skills; therefore the opportunities provide to the child as well as the social’ exceptive affect the development. The objective of this study was to assess and compare the motor development of boys and girls ages from 0 to 18 months. Ninety infants, ages from 0 to 18 (45 boys and 45 girls, stratified by age groups), that lived in the south of Brazil, attending to daycares participated in the present study. The Alberta Infant Motor Scale (AIMS) was used to evaluate motor development. The majority of the infants showed typical development (73.3%); no significant differences between the sexes was found for motor development for the AIMS total scores (p_esc.total = .76; p_percentil = .38) and postures (p_prono = .71; p_supino = .49; p_sentado = .71; p_empé = .97; p_esc.total = .76; p_percentil = .38); non-significant differences’ for association between motor development and sex were found (Eta² = .008; Eta² = .108). In the two first years of life, boys and girls demonstrated similar motor development performance. It is conjectured that the differences between sexes observed latter is affected by opportunities of the environment.
