We've all seen them and maybe you've been one -- parents who get a little too rowdy on the sidelines at youth games.

But First Coast News' Heather Crawford found several tips to help keep parents from crossing the line and how you can help diffuse tense situations on the sidelines.

Earl Newman has two decades of coaching experience. He is now the President of the Greater Jacksonville Pop Warner Football Conference. His advice to parents is to stay calm.

"Before the season starts I have meetings with the parents," Newman said. "Let them know football is not a contact sport, it's a collision sport and kids are going to get dinged up and hurt but in the heat of the game let the coaches do their job and you be a fan and observe the game."

Parents in many leagues including Pop Warner, are required to sign an Adult Code of Conduct -- a zero tolerance policy that includes no foul language, no throwing objects and no intimidation, taunting or booing.

If parents fail to abide, they can be removed or even be barred from future games because, at the end of the day, youth sports should be about having fun.

That's our number one priority, that's one of the things I stress when I'm coaching kids is everyday," Newman said. "After practice I say, 'Is everyone having fun today?'"

Parents and fans on the sidelines should keep their negative thoughts to themselves, treat officials with respect, never address players on the other team except to encourage them and leave the coaching to the coaches.

"It's the coaches job to do that," Newman said. "Once they cross that white line and come on the field they sign the contract they want us to be the coaches so that's what we are here for."

Experts say shouting from the sidelines can distract your child and prevent them from learning the game in a natural way.

The Positive Coaching Alliance says it's important to fill your child's emotional tank to let them know you love and support them regardless of their performance and fill the coach's emotional tank because many times they only hear from parents who have complaints.

Teams may also want to consider designating a "culture keeper" -- a parent who helps maintain the desired youth sports culture.

"If they see their parents behaving like that then that's how they are going to behave," Newman said.
