Responding to a Star Tribune investigation into a rising number of deaths at Minnesota day cares, regulators with the Department of Human Services have called for more training of day-care providers and greater compliance with safe-sleeping requirements.

An Eagan woman faces criminal charges, including two counts of manslaughter, over last summer's death of a three-month-old who was in her care. Authorities say the baby was put down for a nap and died of asphyxiation. The provider was licensed to care for 12 children but had 20 in her home at the time.

Details are emerging in the death of a 3-month-old boy who died while at a Farmington in-home daycare last week. The provider has admitted that the infant was sleeping on a bed and not in crib, but her lawyer says negligence should not be assumed.

The day care provider called 911 after trying to wake up an 8-month-old boy from a nap and finding the child was not breathing. Police say the provider is cooperating and that the child shows no signs of abuse or trauma.

Public records reveal that two child-care centers that failed to follow safe-sleep practices where infants died this year have been shut down by state regulators. A Carver County licensing inspector has also been found at fault for not following through on sanctions in one of the cases, which was discovered just days before an infant's death.

A state official cited an "imminent risk" to children at the Arena Early Learning Center. But the Health Department is not specifying what the problems were. It's only the third time in a decade the department has suspended the license of a child care center.
