Parents are trying to remove the car seats from the necks of their children to make room for more seats for them in a larger car.

A California family says they are among the first to make the move.

The car seats were designed to protect children’s necks and chests when the seats are folded over.

The child car seats are used by more than 2.5 million children across the country.

They were designed with a collapsible neck collar and a seatbelt buckle that can fold up to help protect children.

The parents are asking a federal appeals court to overturn a ruling that said the neck collar was not child-safe.

The families of the three women say they had been told by the car seat manufacturer to remove them.

They say they removed the neck-collar car seat because they had not heard from the company for several months.

They have sued for punitive damages.

The family’s attorney, William McDonough, said the lawsuit is not about money.

He said he has heard of children who have died because of the neck car seats.

The case is a test of how quickly parents can learn about child safety and how easily children can get in and out of car seats, McDonoh said.

The women are not the first people to take up the challenge.

In June, a Florida mother sued after her 4-year-old son was killed by a car seat seat she was holding.

The state appeals court said the suit was meritless.

The American Academy of Pediatrics issued guidelines in 2014 saying that children should not be in cars seat carriers that are too small or too tall.

The CPSC, the nation’s consumer agency, says car seats can be used for safety reasons, including to reduce neck and chest injuries in children.

In its ruling last week, the appeals court cited studies showing that children are more likely to fall or become trapped in a seat when they are in the car.

The court ruled that CPSC must make public the information about the car safety guidelines that led to the lawsuit and said the parents’ lawsuit “would not have been able to succeed without that information.”
