The shooting happened at around 10 p.m. Wednesday as a group of people were standing outside talking, one of them holding the child.
Lt. John Walker tells The Philadelphia Daily News (http://bit.ly/PyxPjY) that just after the men passed the group they turned around and one shouted, "Don't move" before shooting.
A 22-year-old man is in critical condition at a local hospital with a gunshot to the stomach. A 19-year-old woman who suffered a wound to her hand is in stable condition.
Police say the boy suffered bruises when the woman holding him dove to the ground. Two women who were with her were not injured.
