The baby, who was staying at Los Angeles County-USC Medical Center, now weighs 4 pounds 9 ounces.

"I’m just happy she’s doing well. I’m happy that I’m finally going home,” mother Haydee Ibarra, 22, told the Associated Press.

The baby now breathes through an oxygen tube as a precaution, according to the report.

Dr. Rangasamy Mamanathan, who oversees preemies at the hospital told AP he was “cautiously optimistic” the child would develop well “but again there is no guarantee.”

The baby underwent  surgery to close an artery soon after birth.
