Everyone talks about engorgement when milk “comes in”… rock hard b***s. Night sweats.
…but far fewer people talk about the hormonal shift that arrives with it
For many mothers, this starts somewhere between 24–72 hours postpartum
You can go from an emotional high (relief, adrenaline, even euphoria after birth) into a sudden drop that feels surprisingly intense
This is the same window when your body is rapidly transitioning from colostrum to larger volumes of milk
But it’s not just about your breasts, it’s a full hormonal recalibration
After the placenta is delivered, estrogen and progesterone fall quickly
Prolactin rises to build milk supply
Oxytocin pulses to release milk
That rapid shift can land in your body as:
* Weepiness that seems to come out of nowhere
* A sudden mood drop after feeling “up”
* Waves of anxiety or uneasiness, often around feeds
* Feeling emotionally raw, overwhelmed, or shaky
* Night sweats or chills
Some mothers describe it as a wave. Something that builds, peaks, and then passes
Others notice they’re crying without a clear reason, especially in those early days when everything is new and intense
This experience is often called the “baby blues,” and it lines up closely with the timing of milk transition and engorgement. It’s not postpartum depression, it’s a temporary wave of emotions
It’s a reflection of how quickly your hormones are shifting while your body initiates milk production
For most, these feelings are temporary and begin to ease as milk supply regulates and hormone levels stabilize
If emotions feel constant instead of wave-like, are getting heavier instead of lighter, or come with intrusive thoughts or persistent dread, that’s a sign to bring in more support
This early postpartum window is not just about feeding your baby, it’s also a major physiological and emotional transition for you
Feeling weepy, sensitive, or not quite like yourself during this time is a common part of that shift 💛
