WALTHAM, Mass. -- For one Waltham family, Christmas came early this year with a gift that was too priceless to measure.

NewsCenter 5's Rhondella Richardson reported that while many little ones were still snug in their beds on Christmas Eve, the Yang family was headed to the hospital, their new baby girl making her arrival 12 days early.

"We didn't expect a baby so soon. My wife and I had talked about we might have a New Year's baby or something like that, but now we have a Christmas baby. Even better!" said baby Jean's father, Sean Yang.

Baby Jean arrived 10 minutes after midnight, a healthy 6 pounds and 15 ounces.

"This is the second one; everybody tells me it's going to be fast. So, I started contractions in the morning and in the afternoon I started to feel pain, so I called the hospital and I came in," mom Li Huang said.

Jean joined older sister Abigail, who is 2 1/2 years old. Newton-Wellesley Hospital said four babies were born Christmas day and more were expected.
