Answer 1

Infant suckling

Infant suckling is the stimulus that is needed for continued and sustained production of breast milk. When an infant suckles, stimuli are transmitted to the mother's pituitary gland and prolactin (a hormone responsible for milk production) is released by the pituitary and this leads to the production of more milk. The more an infant suckles, the higher the prolactin level and the amount of milk produced.
