Thirty-one-year-old Christina Russin of Sturbridge was killed instantly, while her 9-month-old son Noah passed away at UMass Memorial later in the day.
Now her family is keeping vigil at the hospital for her two-year-old son Carter who survived.
"We're blessed to have Carter after that accident, his mother saved his life. She took the full brunt of that accident...he was behind her in the seat," said his aunt Cheryl Green.
Speaking to us from the hospital, Christina's sister Cheryl Green said they are still trying to process Noah's death.
"He was the happiest baby, I used to call him my fat man and he would just light up, he had the chubbiest little cheeks and he was smiley...and you could see the love he had for his mother and his brothers," Cheryl said.
Cheryl says Christina's oldest son, 11-year-old Isaiah, was thankfully at school at the time of the accident.
