No, but parents should definitely take heed to how their children react to what clothes, shoes, etc are chosen for them. I've always been gnc. I'm pouting or crying in my childhood photos when I'm dressed girly... and smiling when I'm dressed boyish (in simply a basic white tank top and cool shorts). And I hated ponytails and ribbons in my hair. Parents should not force their children to be gender conforming (feminine for girls, masculine for boys). Some toddlers (who are intellectually capable, like I was 😏) are old enough to make those choices. Fortunately, I was born in 1983 instead of 2013... I likely would've been considered trans ~7 years ago.
