The first weeks with a new baby can bring joy, exhaustion and tears, sometimes all before lunch. Mood changes in this stretch are very common. Knowing where the baby blues end and depression may begin helps you, or the people around you, decide when to call.
The baby blues
The American Psychiatric Association (APA) says up to 85% of new mothers experience the baby blues, which it describes as short-lasting and not getting in the way of daily activities.
Sources vary on this. The National Institute of Mental Health (NIMH) says the baby blues are mild, short-lasting mood changes in the first 2 weeks after giving birth, and the CDC says they usually go away on their own within a few days. Seeing a licensed, experienced provider who knows you is essential: they review your symptoms, the risks and the benefits in context and decide the next steps with you.
When it may be postpartum depression
NIMH says symptoms that are severe or that last longer than 2 weeks after childbirth may be signs of postpartum depression, and that most episodes begin within 4 to 8 weeks after the baby is born. Depression can also begin during pregnancy. Clinicians often use the term perinatal depression to cover both, and the APA explains that for this diagnosis, symptoms begin during pregnancy or within a year after delivery. A qualified clinician makes the diagnosis using the DSM-5-TR, the American Psychiatric Association's diagnostic manual.
Signs NIMH lists include a sad, anxious or empty mood most of the day, nearly every day, for at least 2 weeks; hopelessness or irritability; loss of interest; fatigue; changes in sleep or appetite; trouble concentrating; and difficulty bonding with the baby. The CDC adds crying more often than usual, feeling angry, feeling distant from your baby and doubting that you can care for your baby.
It is not your fault
NIMH is direct about this: perinatal depression does not have a single cause, and a woman is not to blame for having it. Life stress, the physical and emotional demands of giving birth and caring for a baby, and hormone changes during and after pregnancy can all play a part. A personal or family history of depression or bipolar disorder raises the risk.
Partners can be affected too
The APA estimates that about 8 to 10% of fathers experience postpartum depression, particularly when the mother is depressed. NIMH notes that partners, family and friends are often the first to spot signs of depression in a new mother. They can help by encouraging a talk with a provider, helping with the trip to appointments and taking on practical jobs such as caring for the baby or the home.

When to get help right away
Thoughts of death, of suicide or of harming yourself or the baby need help now. NIMH also describes postpartum psychosis, a serious illness that can follow childbirth, as a psychiatric emergency. In either case, call 911 or go to the nearest emergency room.
Treatment
NIMH says treatment usually includes therapy, medication or both, and names cognitive behavioral therapy and interpersonal therapy. The APA also lists social support and lifestyle steps. If you are pregnant or breastfeeding, medication when indicated is decided jointly with you, after a careful talk about risks and benefits.
