According to the experts, most children outgrow shyness with time, but for some it lasts into adulthood.

What causes shyness? Some say it's birth order or modeled behavior by shy parents. Or perhaps it's just the way your child is.

"If you have a shy child and the parents don't deal with it off the bat, you are looking at a child who is more likely to feel insecure in school, to develop social anxiety, and eventually what we see is that these children won't even attend school," said Psychotherapist Meghan Lemery.

As a parent, it's hard to see your child struggling with others because they're shy. And be careful not to become overprotective; it makes matters worse.

"I call it the hovering parent. This is potentially not good for a child in developing their social skills and developing their comfort with other peers. The best thing you can do is absolutely attend the event with the child but try to be in the other room so they know they can eyeball you, touch base with you, you are there, they feel secure," said Lemery.

If your child is shy, prepare them for school long before they go.

"Show them their new school," said Lemery. "Take walks by the school, introduce them to their teacher. When you are sitting at dinner, have talks about what kindergarten will be like, really prepare your child."

Never force your child into social situations and be sure to focus on building up their confidence in other areas.

"Whether it's art, whether it's sports, acting and grow their confidence in that area. As you do that and you focus on their talents, they will eventually, hopefully, come out of the social awkwardness," Lemery said.

Children learn by watching others. Parents, that means you. Your ease while approaching others will help your kids.

“When you're approaching others and modeling for your child appropriate social behavior, you always want to make sure you give a warm greeting to the other person you're talking to, make eye contact. Make an effort to be poised and show your child exactly what to do in every social situation,” said Lemery.
