IPhone 5 was erase because of find my phone app?

My little cousin was playing with my food and he earased my iPhone by using the app Find my phone. All my picture are earase, contact and basically everything. Is there a way I can get it back. Do you know who I'm suppose to call.
I had pictures of my dog who well die of cancer soon in it that I will miss please help

I'm sorry to hear about your dog. Unfortunately, I think the only way you can get your things back is through iCloud backup or iTunes backup. Just plug your iPhone into the computer and see if you have the back up. Other than that, I don't think you can get it back.

He probably pressed the erase my phone feature on the find my iphone app. Unless you have recently backed up the information will be lost. You can try to log back into your icloud under settings and sign in with your apple id and password. If you had the photo stream on your pictures will come back to your device.
