Calilse Manning is not only a hero, she's also a big sister! The 4-year-old girl from Kalamazoo, whose mom Centerria is epileptic, called 911 while her mother was having a seizure.

"My mom is really pregnant and she's having a boy and she really needs help," the girl tells the 911 operator in the audio (below) obtained by WWMT.

Centerria was taken to an area hospital where she delivered Calise's little brother TJ Friday morning.

"He's cute and I really love him," she told the TV station.
