Sex-typed play of toddlers in a day care center

By the age of 3, boys prefer gross motor and vehicle play and girls prefer doll and housekeeping play. The present study was an attempt to define the age at which these sex differences first appear by observing the play behavior of one- and two-year-olds in a day care center. We observed use of stereotyped toys in children 15 to 35 months old during free play. Boys played more with the masculine toys than with either of the other types, whereas girls showed almost equal use of all three types. Choice of sex-typed toys was more prevalent among older boys, while older girls showed less play with feminine toys than younger girls.
