It’s occasionally a survival strategy, rodents will eat their young if they are exposed to high levels of stress immediately after giving birth. Some sharks do it in vitro with their siblings.
Edit, higher mammels tend to offer up the ability to sustain the young as a valuable survival trait, except male lions, if a male lion takes over a pride the first thing it does is kill all the cubs so the females go into heat sooner. Nature is harsh.
It makes the stories about the Spartans throwing babies off a cliff make much more sense.
Even as a fully healthy baby your odds were low so if there were any anomalies might as well just remove it from the equation
