Oh yeah - the evil Sim Social Services will swoop in and "rescue" the kid. By rescue, they really mean kill - it is really a death interaction and sets the death type to Neglect, which doesn't even leave a ghost.
Statistic Instance 18282 Child Neglect is how they determine when to destroy your kid. I have removed the actions so it should no longer call the "rescue" routine.
