Mr. Rosen sustained a cut above one eye but refused treatment.

Two other children in the van, ages 3 and 6, were brought to CVPH, where they were treated and released, according to hospital spokeswoman Chris Blake, who confirmed that the baby was transferred to Burlington.

Fletcher Allen did not have any information available about the infant's condition Monday morning.

Driving conditions at the time were very poor, Winter said.

"It was a heavy, wet snow in below-freezing temperatures. Visibility was difficult in the snow."

Multiple callers were able to report the accident from cell phones. Service in the northern exits of I-87 is more reliable than in central sections from exit 33 south to about Pottersville.

Winter said Mr. Rosen may have placed one of the calls.

"We were called by the dispatcher," she said.

An off-duty nurse and her husband were in one of the first cars to come upon the accident and stopped to render assistance, Winter said.

The Rosen family are members of the Orthodox Jewish community and were traveling south from Montreal.

The Hasidic ambulance service in Montreal came to recover Mrs. Rosen's body.

The accident is the third in about nine years to result in the death of either a mother or a child unbuckled from car-restraint systems to breast-feed, Winter said.

Around 8:22 p.m., Jean Lafranc, 56, of Montreal, was driving a 2000 Ford Econo van north on I-87 when he tried to pass another vehicle.

The van went out of control, slid off the west side of the highway and rolled over twice.
