A little snippet of knowledge for those who are interested, gleened from Wiki:

Filicide is the deliberate act of a parent killing his or her own son or daughter. The word filicide derives from the Latin word filius meaning "son".

A 1999 US Department of Justice Study concluded that between 1976 and 1997 in the United States, mothers were responsible for a higher share of children killed during infancy while fathers were more likely to have been responsible for the murders of children age 8 or older.

Furthermore, 52% of the children killed by their mothers were male (maternal filicide), while 57% of the children killed by their fathers were male (paternal filicide).

Prolicide is the killing of offspring.
Infanticide is the killing of an infant from birth to 12 months.
Patricide and matricide are the converse of filicide: the killing of a parent by his or her child.
Fratricide and sororicide refer to the killing of one's sibling.

And as for non-familial killing terms from the same root:

Regicide is the killing of a king or ruler.
Tyrannicide is the killing of a tyrant.
Homicide is the killing of a human.
Genocide is the killing of an ethnic, religious or national group.
Suicide is the killing of oneself.
Deicide is the killing of a god.
Uxoricide is the killing of one's wife.

Also consider filial cruelty (cruelty toward one's own child), child cruelty (cruelty toward an unrelated child), and child murder (the murder of a child in general).
