One thing I have learned about parenting is that kids grow up in stages.
Just when you think you have one stage figured out, circumstances change, and suddenly your child is thrown into a NEW stage that puts you back at square one.
In preschool and kindergarten, boys and girls become friends. They invite each other over to play and don’t really see their differences. But around first grade, the two genders part ways. Invisible lines get drawn, and the boys hang out with boys, and the girls hang out with girls. They fall off each other’s radar until typically the spring of fifth grade, when they notice each other again.
In middle school, the boy-girl interactions amp up. They get crushes and have awkward conversations. Since their relationships are short-lived, a parent’s concerns are short-lived too. Give it a week, and a break-up is forgotten.
