Weaning & Hormones: What Happens When You Stop Breastfeeding
Weaning triggers a hormone shift: prolactin drops, estrogen rises, and cycles often return or regulate. Many women feel emotional, sometimes unexpectedly sad or irritable. Gradual weaning eases the transition. Periods typically return or become more regular after weaning.
What to expect
Weaning is a hormonal event, not just a feeding change.
- Prolactin drops; estrogen and progesterone rise.
- Mood changes, including sadness or irritability, are common.
- Periods often return or become more regular.
- Gradual weaning is easier on your body and emotions.

Frequently asked questions
Why do I feel sad after weaning?
Dropping prolactin and shifting hormones can cause unexpected sadness, anxiety, or irritability. It is a normal physiological response and usually passes within a few weeks.
Will my period come back when I wean?
For many women, yes. If your period had not returned, it often comes back within a few weeks of significantly reducing or stopping breastfeeding.
