Dealing with misbehavior

Jade
Hi mommies! How do you deal with your child's misbehavior? Also, how old are your children? 
I'm a mom of 3, with a husband who works long hours. Recently dealing with some bad behavior and my approach doesn't seem to be working like it used to. Just looking for some fresh ideas...thanks!!
I do have a Kik for anyone who wants to talk further.😊
