If your child ever goes missing, your initial response will likely be to panic. Law enforcement wants to know every physical detail of your child, but all you want to know is where he or she is.

The FBI created an app to help parents compile the information they need - just in case.

The "Child ID" app can organize important information like your child's height, weight and hair color. You can upload photos of them, plus any identifying characteristics on their body, such as birthmarks.

It also lists steps you should take in the first 24 and 48 hours after your child goes missing.

KWCH personal protection expert, Joe Schillaci says Spring Break is a perfect time to download the app and add as much information as you can.

"I'm at a mall and my son's running around and he's playing in a coat rack and he comes up missing for even 10 seconds and I'm screaming at the top of my lungs for him and it's a total and complete panic," Schillaci told us. "And I'm 30 years in law enforcement so you can only imagine a parent that has a child that comes up missing – really missing – the amount of emotion is overwhelming."

He says it's also important to talk with your children about basic safety tips, especially if they could be home alone - or on a trip.

"Me looking at it last night reminded me – with all of these years of experience – to talk to my 5-year-old, to talk to my 15-year-old step son, to remind them, 'Hey, you don't accept anything from any stranger without us being there, without knowing'," said Schillaci.'

The FBI says the app has been downloaded more than 300,000 times since it was first created in 2011.
