According to investigators, the toddler apparently reached for an iPod but found the loaded weapon. Police believe the shooting to be accidental.

The bullet first struck his father in the buttock and then hit the right shoulder of his mother, who is eight months pregnant, police said. His 2-year-old sister was present but unhurt.

Both injuries are non-life threatening, authorities said.

Justin Reynolds told KOB-TV (http://goo.gl/gRCXe0) that he and his girlfriend, Monique Villescas, were getting ready to order pizza when the toddler fired the shot.

"It was like if I was to get up shake your hand and sat back down. That's how fast it happened," Reynolds said." All of a sudden we heard a gun go off and the next minute I realized my girlfriend was bleeding. Then, I sat down and realized I was shot, too."

Reynolds said he called 911 and grabbed some towels to try to stop her bleeding.
