Crushes and “cooties” are everyday issues.
Children want to know what makes boys and girls different, personally and physically. This curiosity, as well as a heightened awareness of friendships, results in second graders having attractions or revulsions to members of the opposite sex.
What you should do: Talk, talk, talk. Realize that crushes feel real to children, even though they may seem silly to you, and be sensitive if your child is heartbroken. Establishing trust now might pay off in later years, when relationships take center stage.
