Are you confused by your tween’s erratic behaviour? You know what we mean—one minute she’s happily telling you about how her day went, the next, she’s running up the stairs and locking herself up in her room. In case you’re worried that your own child is the only one acting this way, let us tell you right now that this kind of behavior is really not that uncommon.

While the Wall Street Journal reports that there are studies that show “20 percent of teenagers have a psychiatric illness with depression, anxiety and attention-deficit hyperactivity disorder being among the most prevalent,” it is unlikely for your tween to end up in that category.

Tweens can be quite unpredictable at their age, their emotions even more so. As a mom, you might feel like your tween is slipping through your fingers, making you want to reach out to her even more. We’d like to help you out with that. Scroll through the gallery for some of the ways you can deal with a moody tween.
