The 28-year-old mother, who was not identified, has been diagnosed with schizophrenia, Baltazar Israel, police superintendent in Ilagan, Isabela province, told ABS-CBN News.
"According to her sister, she had a previous medical record. She was previously given medical attention but her medication was halted due to financial problems," he said.
The 1-year-old victim's heart was missing, and police are investigating whether the mother ate it or threw it away.
Neighbors called police Tuesday when they saw the woman carrying a sack. She was caught as she tried to discard it, and the body was found inside, its throat cut. Blood was seen spilling from the mother's mouth.
The mother and child were alone at home at the time, but the woman's partner said she was looking for a knife before he left.
