Now this is a unique story. A baby was born on a CTA bus during the busy Wednesday morning commute. Guadalupe Lara, 33, thought she would make it to the hospital on time after she felt contractions, but her baby just couldn’t wait. Samantha Centeno-Lara was born weighing 7 pounds, 7 ounces. She wasn’t expected for another week, but on Wednesday morning, her mom felt herself going into labor.
