If your child breastfeeds less often, you will not make as much breast milk. Not only can it decrease your breast milk supply, but excess alcohol can affect your ability to tend to your child's needs. Alcohol also passes into your milk which can put your baby at risk for a developmental delay.
First of all, is your milk supply really low? Often, mothers think that their milk supply is low when it really isn't. If your baby is gaining weight well on breastmilk alone, then you do not have a problem with milk supply. It's important to note that the feel of the breast, the behavior of your baby, the frequency of nursing, the sensation of let-down, or the amount you pump are not valid.
This is because her breast can store up to 300 ml breast milk (roughly), so even with the pumping schedule change, her milk supply is still stable. Let's compare with mom B. She also got 600 ml of milk with 3 pumping sessions at work, but when she reduced it into two, she could only get 500 ml total.Author: Rina.
