Mammal Lactation
Lactation in mammals is a positive feedback loop, because milk is continually produced until the offspring stops breastfeeding. The response increases the stimulus. It is not negative, because it does not seek to limit a detrimental stimulus. In this case, the stimulus is the baby suckling, which results in signals being sent to the hypothalamus that then releases oxytocin, which in turn results in continued milk production. This does not end until the baby is done suckling.
