In the incident, the infant "hit its head on the footstool and then the child started crying", District Attorney Wade Newell said, according to WEAU. A judge set bond at $50,000 (€44,000).
All members of the group - seven children and five adults - "were in the ditch, not on the pavement or gravel shoulder at the time of the crash" and were "wearing green highly visible safety vests", police said.
The grandmother of one of three Girl Scouts killed in a Wisconsin hit-and-run crash says the child dreamed of being an animator and shared a love of crafts with her mom, who also died in the accident.
The girl was in foster care at a home in Tilden, a town almost 200 miles northeast of Madison that also serves as a day care centre, when she accidentally dropped the infant who hit his head on a stool and began to cry, WEAU News reported, citing Chippewa County District Attorney Wade Newell.
The 21-year-old had nothing to say in court Tuesday, while appearing by video from the jail.
The girl, who was charged with first-degree intentional homicide, appeared in court Monday morning.
Treu said he did not pass out, but he did lose controlling of the vehicle and fishtailed after his passenger grabbed the steering wheel from him.
Two cities will split Amazon HQ2

The girls were collecting trash next to a rural highway over the weekend when a pick-up truck hit them.
The traffic crash claimed the lives of Jayna S. Kelley (age 9) of Lake Hallie, Autum A. Helgeson (age 10) of Lake Hallie, Haylee J. Hickle (age 10) and her mother Sara Jo Schneider (age 32) from the Town of Lafayette.
A woman with the group and three Girl Scouts - including her daughter - were killed, and a fourth girl was critically injured.
Authorities are recommending 13 charges against Colten Treu, including four counts of homicide by intoxicated use of a motor vehicle. Authorities said Treu sped off after the collision, but surrendered hours later.
She had been placed in foster care with the family that runs the daycare centre.
Jensen says Treu will have a bond hearing at 10 a.m. Monday.
In court, Newell said a medical pathologist believed the baby's injuries were consistent with a fall and the tread marks on his head matched those of the suspect's shoes.
