The Emotional Impact of Weaning and Breastfeeding Hormones.
Weaning a baby off breast milk can cause mood swings, sadness, and even depression in the breastfeeding parent due to hormonal changes. Hormones responsible for lactation, prolactin and oxytocin, also contribute to feelings of calm and contentment, so as they decrease, mood can dip. The impact of hormonal changes after weaning can vary depending on the age of the baby, how frequently the parent is still nursing and/or pumping, and how swiftly weaning occurs. These feelings are temporary and will subside as the parent and baby adapt to the new routine, which usually takes no more than two weeks.
