At age 4, my kids were attracted to "The Lone Ranger" and "Hot Wheels Cars", respectively. Suppose I can get a grant to study them?
4 years old....jeez, I bet the publishers of this "study" don't have kids of their own. Or, they have an agenda. Or, both.
I’ve raised four children (two boys/two girls), and my oldest granddaughter. NONE of them showed any interest in the opposite sex until, at the earliest, 11 or 12 years of age. NONE of them exhibited any indications of sexual identity/persuasion, other than normal curiousity, before age 10. These loons who spew such crap about sexual orientation being fixed by age four need to be publically flogged.
at four girls are still icky. it is an attempt to keep opposit sex “icky” through puberty to cement the inability to grow up.
