BELLEFONTAINE, Ohio (AP, WLWT) —

A woman calmly called 911 to report her baby son wasn't breathing on Tuesday and then hours later confessed to killing him and her two other young sons over the past several months, police said.

Brittany Pilkington was charged with three counts of murder and was jailed Tuesday, said police in Bellefontaine, about 60 miles northwest of Columbus.

Pilkington, who's 23 years old, is accused in Tuesday's death of 3-month-old Noah Pilkington and in the deaths of 4-year-old Gavin Pilkington, who died in April, and 3-month-old Niall Pilkington, who died in July 2014. No working telephone number for her home could be found, and no attorney information was available for her.

Police said officers went to the family's apartment shortly after 3 a.m. after an emergency call from the mother saying that Noah wasn't breathing. They said she calmly answered a dispatcher's questions while the baby's sleep apnea alarm beeped in the background. The baby was pronounced dead at a hospital.

“Our son’s (inaudible) alarm is going off. He’s not breathing,” Pilkington told the 911 operator.

It wasn't the first time she'd made a call to 911.

Authorities already were investigating what happened to Niall and Gavin, whose causes of death still hadn't been conclusively determined. In each of those cases, their father, Joseph Pilkington, found them unresponsive when he got home from work.

"Our son's not breathing," Brittany Pilkington said meekly to a dispatcher when she called police on April 6 as her husband frantically gave Gavin chest compressions. "He's turning white."

In each incident, the children's father, Joseph Pilkington, returned home from work to find the kids unresponsive, officials said.

Joseph Pilkington can be heard in the background of one 911 call begging his son to wake-up.

"Gavin, wake-up buddy,” Joseph Pilkington said.

Joseph and Brittany Pilkington were cooperative on Tuesday, police said. She eventually told detectives that she killed all three children, police said, but no other details of officers' discussions with her were released.

"The tragic deaths of Niall, Gavin and Noah leave a pit in our stomachs today," police Chief Brandon K. Standley said in a statement. "Our condolences go out to the remaining family members who have supported this family through a very difficult 13 months."

Neighbors wondered why it took police so long to figure out the children's deaths were suspicious.

"Why didn't this get stopped and somebody go to jail after the first child? It took Logan County three kids before anything happened. Obviously something was going bad when the first kid died,” said neighbor Anna Roe.

Brittany Pilkington has been charged with three counts of murder.

She will make her first court appearance Wednesday.
