In June, law enforcement officials found the remains of Tylee Ryan, 17, and JJ Vallow, 7, on rural property in Fremont County, Idaho, belonging to Daybell, who is married to the children's mother, Lori Vallow.
Vallow was charged in March with two felonies after a deadline to turn over her children to authorities passed.
Madison County Prosecuting Attorney Rob Wood said Daybell helped hide evidence in that case.
Authorities have not said how the children died and no one has been charged with killing them.
Authorities in June used pings from the cell phone of Vallow's now-deceased brother, Alex Cox, to pinpoint potential search areas on Daybell's property.
Vallow had already been jailed on two felony counts of desertion and nonsupport of children and three misdemeanor charges.
Last month, prosecutors added the same charges as Daybell, but she has not appeared in court on those counts.

Congress could pass a new law setting a different national election date, but that would require majority votes in the Democratic-controlled House and the Republican-controlled Senate, plus the President's signature.
First, as to the military, under the Insurrection Act of 1807, the president has authority to deploy federal troops in certain circumstances: (1) where requested by a state governor, (2) where necessary to "suppress" unlawful "obstruction" or "rebellion," or (3) where required to prevent interference with enforcement of federal or state laws.
