The shooting occurred at about 6:20 p.m. in the 6300 block of South Seeley during a "family gathering," said Chicago police spokesman Anthony Guglielmi.
An 8-year-old boy was once in the chest and once in the back. A 10-year-old girl was shot in the shin. Both of the children were taken to Comer's Children Hospital in stable condition, according to Chicago police.

No one was in custody Saturday evening.
The circumstances of the shooting were immediately unclear. The gathering was a baby shower.
