Newly clingy 3yo. Idk what's going on, but he had become OVERLY Clingy. Extra kisses, hugs, he has to be by me every waking minute. I am a teacher and here lately I've been floating to my son's school occasionally. Normally when I float to his room he pays me NO MIND, here lately if I walk by the room and he sees me, his teacher will call my class and have me come see him. Has anyone else had this problem? Could this be an early sign of pregnancy??
