The amount of breastmilk that flows is directly proportional to the suckling of your breast. If the suckling strength is strong, the more the breastmilk will flow over time. Suckling stimulates 2 major hormones involved in milk let down - Oxytoxin and Prolactin. These 2 hormones produced during breastfeeding work together to make milk, establish milk letdown and keep up with the supply and demand of a nursing infant. However, in some cases if baby cannot suckle strong enough for milk let down, we recommend your partner /husband to help in initial suckling to trigger the process.
