It's a busy time for everyone with the start of a new school year.

But experts say keep a look out for anxiety that your child might be experiencing.

Dr. Stephanie Slock, a pediatrician with  Aurora Health Care, was a special live guest on the CBS 58 News at 4 p.m.

Dr. Slock says there are some key behavioral changes that should raise red flags.

They include changes in sleeping habits and appetite.

Or anxiety may manifest itself in the form of tantrums or being withdrawn.

\"Be open with them and let them know you're an ear to listen or shoulder to cry on,\" explained Dr. Slock.

You can't force the conversation and you can't promise to fix it. But you can let them know you're always open to what they have to say.

Children might also feel more comfortable with talking to their physician.

You can't force the conversation. Usually you have to wait for them to bring it up.

That's why it's important to communicate that you're ready and waiting when they need you.

\"You're not there to judge. You're ready to listen.\"

Dr. Slock says anxiety can come just from having to change classrooms in middle school or high. 

\"I feel it's mostly just to fit in. For male students it's fitting in on the sports team. For female students, it could be about weight or being part of the popular crowd.\"

Dr. Slock also says students can feel extreme pressure and anxiety over their grades.

A sudden slip in grades is also a sign that it's time to call the family physician.

\"I would keep your eye out . If your child withdraws from normal activities or their grades are falling. It's a sign that it's something more serious.\"
