A pregnant suburban Chicago woman felt contractions a few minutes after finishing the Chicago Marathon and gave birth hours later to a baby daughter.

Amber Miller was nearly 39 weeks pregnant when she started the 26.2 mile race on Sunday morning. Her daughter June was born at 10:29 p.m. weighing 7 pounds, 13 ounces.

Sure, call it sweet. Call it adorable. But today June is shaking her rattle whether she wants to or not.
