Elementary school students sometimes practice "relationships". They certainly do it in their friendships. When the mean girls do their thing in 3rd grade, I'd rather they get it out of their system and they learn things there than take it into a workplace, wouldn't you? So they practice their love relationships too. Now, when a parent hears that their 4th grade girl has a boyfriend, they get all nervous because they're thinking of an adult relationship. But this is mostly role playing, it's mostly child's play, it's mostly fantasy and often the guys know nothing about it, by the way, because the girls mature faster and they're the ones more into it. I would be concerned if you're finding out that there's actual, physical touch going on, because usually in elementary school, the boys and the girls each have codies and they don't want to touch each other until they come back to middle school. So if there's physical touch going on, I would be concerned. But otherwise, this is the way they learn to love and live and break up and be together, and learn that they're okay and learn to relate. So I think it's important sometimes that some kids do practice this. And for the most part, it's fantasy. It's important that parents not project their own ideas of what a boyfriend is on a 4th grader because it doesn't mean that to him and her.
