BOSTON (CBS) – A 10-year-old girl from Taunton is foregoing birthday gifts this year to raise money to help her unborn sister, who has been diagnosed with a rare condition.

WBZ NewsRadio 1030′s Doug Cope reports.

Isabella Coute’s unborn sister has been diagnosed with congenital diaphragmatic hernia (CDH), which leaves a hole in the diaphragm.

“My baby sister Ava is diagnosed with CDH, so I figured I would donate that instead of getting gifts,” said Isabella. “I have everything really that I need.”

This isn’t the first time she’s raised money for charity, according to her mother, Roni Coalfield.

“The past three years, she’s given up all of her gifts in lieu of donations for different causes, which is pretty awesome,” said Coalfield.

The baby will undergo surgery at Children’s Hospital after she’s born.
