(well not for whatever reason, breast feeding reduces stress by releasing a chemical into the females body).

Then going back to other species. There are assorted breeds of ants that have their favorite type of plant and on it they selectively allow so many aphids to live, even though aphids kill plants. The reason for this though is so those ants can harvest the milk from the aphids to consume.
