Parenting ordinarily is difficult, but if you want to get stuck at being an ordinary parent, then pray your children to skip the teenage part of their lives and evolve straight to being adults. Because then at least will you get saved from the headaches and troubles the teenagers give their parents. But then again, what fun will it be if we do not get to experience the same things we put our parents through when we were also teenagers, and who even wants to remain ordinary in this world of ours?
Dealing with teenagers takes a lot of patience, and one of the major things that makes it difficult is their moods, but here is how to handle them;

Go with the flow: There is always an aura surrounding every mood change or behavior, and this cannot be predictable, but the best way to cope with it is to try to understand. We get to know the moods our teenage children with their behavior and how they respond. So it is always best to avoid adding to the pile of things that are making them moody and try to give them the space they think they need. Like it is usually said, let sleeping dog lie.

Scream at them when it is out of control: Sometimes these things can get out of control, I mean it can get in their heads, and then they start misbehaving, then the need for checks and balancing comes in. Letting sleeping dog lie does not necessarily mean they are sleeping, it just means do not disturb them. But what if it is this disturbance that can bring them back to their senses? And not just disturbance this time around, scolding! Then it needs to be done because being too loose might just mean being out of control.
Let them know to throw tantrums now and then is not OK: Most times, teens respond to their moodiness by throwing tantrums. Meaning they mostly childishly express themselves. While it might be acceptable to some extent, it is also best to inform them that the habit of doing so is not good enough and should be corrected.
