heteronormativity include sexual behavior, but mostly contains other behavior. Like the way you dress, talk or present yourself, the activities or kind of play you do or like. Parent comment is mostly talking about non-sexual heteronormativity, which is often presented as the norm. An obvious example would be an adult insisting that pink is for girl and blue for boys, and shaming a kid for liking what's not the (hetero-)norm.
