Michele Kalina, 44, was arraigned on charges of homicide, aggravated assault, endangering the welfare of children, reckless endangerment, and abuse of a corpse.
Also during the hearing, the judge issued a gag order in the case. The gag order prevents anyone involved in the prosecution or defense of Kalina from talking about it publicly.
Investigators said Kalina hid all five sets of remains in a closet inside the apartment building in the 700 block of Court Street in Reading where she lived with her husband and teenage daughter.
"These remains were all badly decomposed skeletal remains," Berks County District Attorney John Adams said previously.
They said at least four of the five babies were the product of an extramarital affair between Kalina and her boyfriend.
Adams said Kalina lied to her husband and her boyfriend to mask her pregnancies and gave her family strict orders not to go in the closet.
Kalina's daughter broke that rule, found the containers, and tipped off police, investigators said.
Upon further investigation, detectives said Kalina's daughter also unknowingly threw out one of the sets of remains.
It was later found by a cadaver dog at the Conestoga Landfill in New Morgan.
