No parent likes giving the same instruction over and over again only to have it ignored. When parents reached this stage, they think their only course of action is to get their child's attention by yelling.
While yelling may get your child's attention, it can initiate their flight or fight response that will make it more difficult for them to do what you wanted of them in the first place.
There is a better way to engage with your child that creates connections. You develop better relationships with your child by investing in behavior skills and teaching your child your expectations. 
The behavior skill Following Instructions teaches your child how to listen and do what you want them to do without either of you getting frustrated or angry, reducing stress and frustration.
Think of what your family life would look like if when you asked your child to do something, they did it without complaining? Wouldn't that change the whole dynamic of your family? 
Teaching a new behavior skill requires work and time, but we promise that the long-term payoff will be incredible. It will change how your family interacts. You will find that your home is a calmer, happier, and more wonderful place.
