The birth of a baby can trigger a jumble of powerful emotions, from excitement and joy to fear and anxiety. But it can also result in something you might not expect — depression. Most new moms experience postpartum "baby blues" after childbirth, which commonly include mood swings, crying spells, anxiety and difficulty sleeping. Baby blues typically begin within the first two to three days after delivery, and may last for up to two weeks. But some new moms experience a more severe, long-lasting form of depression known as postpartum depression. Rarely, an extreme mood disorder called postpartum psychosis also may develop after childbirth. Postpartum depression isn't a character flaw or a weakness. Sometimes it's simply a complication of giving birth. If you have postpartum depression, prompt treatment can help you manage your symptoms and help you bond with your baby.
