Being a tween — the stage between childhood and the teenage years — can be difficult for a girl. On the one hand, she is trying to separate from her parents' influence and become an independent person. That means letting go of the comfortable and secure hands of her parents or caregivers. On the other hand, she is beginning to experience huge changes in her body, which means she needs her parents more than ever. So expect your daughter's tween years to be turbulent, tumultuous, and with your guidance, terrific.
