Is there available recent data that shows any sort of gender disparity in the act of murdering someone's own child ?

I just spent two hours in a class where we were told that men are violent and thus are the majority of domestic abusers etc and the speaker went on to explain how terribly dangerous this is for children, implying that the "inane masculine violence" is a high risk for babies. This was unusual.

What are the stats on infanticide and neonaticide ?
