Full Breast or Empty Breast? What You Need to Know About Breast Milk Production
Dear mothers, similar thoughts go through the minds of many mothers during breastfeeding:
- “My baby is constantly sucking, no milk accumulates in my breasts.”
- “My breasts get soft in the evening, I think I'm running out of milk.”
- “If I breastfeed before my breasts are full, my milk will not be enough.”
- “Let me wait a while, let the milk be stored, then I will breastfeed.”
Although these thoughts are quite common, they are some of the most common misconceptions about breast milk production.
Tits Are Not a Warehouse
The most important point to know about breast milk production is this:
Breasts do not work like a milk tank.
The body constantly produces milk, and this production is largely shaped by the baby's breastfeeding frequency.
So frequent breastfeeding does not reduce milk supply, on the contrary, it supports milk production.
Does Softening of Breasts Mean That Milk Has Ended?
No.
Many mothers notice that their breasts become softer, especially later in the day, and think this means their milk supply is decreasing.
However, softening of the breasts does not always indicate a decrease in the amount of milk.
As the breastfeeding process settles down, the breasts adapt to milk production and the initial feeling of fullness may decrease. This is completely normal most of the time.
Does Milk Decrease in the Evening Hours?
Some mothers observe that their breasts feel emptier in the evening and their babies want to breastfeed more often.
This does not usually mean that milk production has ended.
Breast milk may show different characteristics throughout the day. Although the amount of milk seems relatively less in the evening, the fat content may increase. Therefore, there is no need to worry about milk quality.
Does Milk Decrease as You Breastfeed?
On the contrary.
Breast milk production works with the supply-demand system.
As the baby sucks:
- The breast is stimulated more frequently.
- Milk production hormones work more actively.
- The body receives the message that it needs to produce more milk.
Therefore, frequent breastfeeding is one of the most important mechanisms that increase milk production.
What Does Full Breast Mean?
Breasts that are not emptied for too long may give the following message to the body:
“There is enough milk now, you can slow down the production a little.”
For this reason, the milk production rate may decrease over time in breasts that remain constantly full.
Regular emptying of the breast through breastfeeding or expressing is important for the continuity of milk production.
Is it right to wait until the breast is full to breastfeed?
No.
Extending breastfeeding intervals simply by waiting for the breasts to fill may cause decreased milk production in some mothers.
Especially in the neonatal period, breastfeeding the baby according to its hunger signals helps regulate milk production.
Difference Between Full Nozzle and Empty Nozzle
Overall:
Full Breast
- It has not been emptied for a longer period of time.
- Milk production may tend to slow down.
- The fat content may be relatively lower.
Regularly Emptyed Breast
- Stimulated more frequently.
- Milk production continues more actively.
- It may contribute to the intake of milk with higher fat content.
Result
Breast milk production is supported by regular and effective breastfeeding, not by waiting for the breasts to fill. Softening of the breasts often does not mean that the milk has run out. On the contrary, as the breastfeeding process progresses, the breasts learn to work according to the baby's needs. Therefore, one of the most effective ways to increase milk production is to breastfeed your baby as needed and ensure that the breasts are emptied regularly.
