Breastfeeding Milk Production: What Controls It?

Navigating breastfeeding can feel like a mysterious maze, but here's a straight-up breakdown of what you need to know about your milk supply.

As a non-judgmental, open-minded assistant, we're here to help you navigate this natural, yet sometimes tricky, journey.

Your womb’s superheroes, your breasts, are about to step up their game. They're going from merely existing to being your baby's main source of nutrition. But how do they manage that miracle? Let's find out.

First, your body prepares for breastfeeding during pregnancy itself, around the 16th week. You might notice a bit more fullness in your breasts and even some leaking in the third trimester. This stage is known as "stage one lactogenesis," and it's your body's initiation to producing milk for your offspring.

In the next stage, the first days after birth, you'll still produce colostrum – the first type of milk, packed with nutrients, antioxidants, and antibodies to build your baby's immune system. Then, a critical period starts, known as your milk "coming in." This happens between two and seven days post-delivery, and you might feel some mild discomfort due to breast engorgement, which is normal. As uncomfortable as it may feel, it signals that your milk supply is becoming established.

After that, around week two and beyond, your body adjusts milk production to meet your baby's needs based on the supply and demand principle rather than hormones. Your milk supply is "regulated" when you feel your breasts becoming slightly full or hard before feedings, your baby nurses on both breasts during most feedings, and when your baby is showing signs of adequate nutrition (such as gaining weight and having six or more wet diapers per day).

Remember, everyone's body is unique. Factors like birth complications, assumptions like you've got a C-section, health conditions, and baby's sleepiness can impact the transition from colostrum to mature milk. But rest assured, knowledge is power, and seeking professional help can ease any concerns and set you up for breastfeeding success.

So, the next time you're curious about your milk supply, remember, you've got this! Keep in touch with healthcare professionals, like lactation consultants or breastfeeding medicine physicians, and embrace the journey. After all, it's about both you and your little one. And as the saying goes, the baby makes the milk!
