Postpartum depression (PPD) is depression that starts in pregnancy or in the year after birth. It affects about 1 in 7 women worldwide. In India the figure is higher: a meta-analysis of Indian studies put it at 22%, and another at 23.5%, close to one mother in four.
This guide covers how to tell PPD from the baby blues, when it starts, how long it lasts, treatment while breastfeeding, and how partners can help.

Baby Blues vs Postpartum Depression: How to Tell the Difference
Up to 80% of new mothers get the baby blues. You cry at an advert, then feel fine an hour later. The blues peak around days three to five and fade within two weeks without treatment.
Postpartum depression is heavier and it stays. The low mood does not lift between episodes, and it gets in the way of looking after yourself or the baby.
| Baby blues | Postpartum depression | |
|---|---|---|
| How common | Up to 80% of mothers | About 1 in 7 (1 in 4 in India) |
| When it starts | Days 2 to 5 after birth | Any time in the first year, often weeks 2 to 12 |
| How long it lasts | Under 2 weeks | Weeks to months, sometimes years without treatment |
| Mood | Swings up and down | Low most of the day, most days |
| Daily life | You can still cope | Caring for yourself or the baby feels impossible |
| Treatment | Rest and support | Therapy, medication, or both |
One test that doctors use: when the baby sleeps, can you sleep? If you lie awake because your mind will not stop, that points away from ordinary tiredness and toward depression or anxiety.
Signs of Postpartum Depression in New Mothers
PPD does not always look like sadness. Many mothers feel numb or on edge rather than tearful. Common signs include:
- Low mood or emptiness on most days for two weeks or more
- Losing interest in things you used to enjoy, including the baby
- Feeling like a bad mother, or that the baby would be better off with someone else
- Anxiety, racing thoughts, or panic attacks
- Sleeping badly even when you get the chance
- Big changes in appetite
- Trouble making small decisions
- Pulling away from family and friends
- Thoughts of self-harm or of not wanting to be here
Postpartum rage
Some mothers mainly feel anger: shouting over small things, then shame. Postpartum rage is not a separate diagnosis, but it often comes with depression or anxiety, usually between six weeks and a year after birth. If anger is what you notice most, tell your doctor.
Intrusive thoughts about harming the baby
Between 70% and 100% of new mothers have sudden, unwanted thoughts of the baby getting hurt, and nearly half have a flash of a thought about hurting the baby on purpose. Because these thoughts horrify the parent, they do not raise the risk of harm. If they take up hours a day, or you start avoiding the baby or hiding knives, that suggests perinatal OCD, which responds well to treatment.
Thoughts that feel reasonable to you, or voices telling you to act, are different. See the section on postpartum psychosis below.
When Does Postpartum Depression Start, and Can It Start Months Later?
Most cases begin within the first three months, and the most common time is around six weeks. PPD can also begin during pregnancy, which is why doctors now use the term “perinatal depression.”
Late-onset postpartum depression appears 6 to 12 months after birth, often after weaning, going back to work, or months of broken sleep. A mother who felt fine at her six-week check can still develop PPD at eight months, and it is treated the same way.
How Long Does Postpartum Depression Last?
With treatment, many women feel better within a few months. Without it, PPD can drag on: a US National Institutes of Health study of about 5,000 mothers found roughly 5% still had high depressive symptoms three years after birth.
What Causes Postpartum Depression?
Several factors usually stack up:
Hormones. Oestrogen and progesterone fall steeply after birth, and some women are more sensitive to that drop. An underactive thyroid after delivery mimics depression, so ask for a thyroid test.
Sleep loss. Weeks of broken sleep affect mood on their own. Our guides to sleeping when the baby sleeps and sleep for nursing mothers have practical ways to protect it.
Physical recovery. Pain from stitches or a C-section wears you down. Our guide to postpartum recovery and healing covers what is normal.
Personal history. A past episode of depression or anxiety, depression during pregnancy, or PPD after an earlier baby all raise the risk. So does a family history.
Circumstances. Money worries, marital conflict, a traumatic birth, a baby in the NICU, and domestic violence are all linked to PPD. Indian studies also find higher rates when a family wanted a boy and the baby is a girl.
Postpartum Depression Test: How Screening Works
Doctors most often use the Edinburgh Postnatal Depression Scale (EPDS). It has 10 questions about the past seven days, scored from 0 to 30. A score of 13 or more suggests depression is likely. Any answer other than “never” to the question about self-harm needs follow-up whatever the total.
You can take the EPDS online, but it screens rather than diagnoses, so take your score to a doctor. The American College of Obstetricians and Gynecologists recommends screening during pregnancy and after birth. If nobody has asked, raise it yourself.
Postpartum Depression Treatment Options
Talking therapy
Cognitive behavioural therapy (CBT) and interpersonal therapy (IPT) have the best evidence. CBT targets thoughts like “I’m failing at this.” IPT focuses on relationships and the role change a baby brings. For mild to moderate PPD, therapy alone is often enough.
Antidepressants
For moderate or severe PPD, doctors usually add an SSRI antidepressant. These take two to six weeks to work, so an early prescription matters.
Zuranolone
In 2023 the US FDA approved zuranolone (Zurzuvae), the first pill made specifically for postpartum depression. You take it once a day for 14 days, and some women improve within days. Its predecessor, brexanolone, needed a 60-hour hospital drip and left the US market in January 2025. Zuranolone causes strong drowsiness, so no driving for 12 hours after each dose. It is not widely available outside the US yet.
Other help
Treating a thyroid problem or anaemia can lift mood. Peer groups, such as those run by Postpartum Support International, connect you with women who have been through it. For severe PPD that does not respond to medicine, some hospitals offer TMS or ECT.
Can I Take Antidepressants While Breastfeeding?
Yes, in most cases. Sertraline is the antidepressant doctors prefer for breastfeeding mothers. Only tiny amounts reach breast milk, and studies of breastfed babies have not found clear side effects. Doctors usually start low and ask you to watch for poor feeding or unusual irritability in the baby, especially if premature.
Untreated depression carries its own risks, and stopping breastfeeding to avoid medication is rarely necessary. Our article on mental health and breastfeeding looks at how the two affect each other.
Zuranolone is less settled. Studies find very little of it in breast milk, but the manufacturer’s label still advises caution, so decide with your doctor.
Postpartum Psychosis: When It Is an Emergency
Postpartum psychosis affects 1 to 2 in every 1,000 mothers. It usually starts suddenly in the first two weeks, sometimes within 72 hours of birth. Restlessness and not sleeping at all come first, then confusion, rapid mood swings, hallucinations, and strange beliefs, often about the baby. Women with bipolar disorder face the highest risk.
It is a medical emergency. Go to hospital the same day. With fast treatment, most women recover fully.
How to Help Your Wife or Partner With Postpartum Depression
Partners often notice the change before the mother does. What helps:
Name it gently. “You don’t seem like yourself, and I’m worried. Can we talk to the doctor together?” Then book the appointment and go with her.
Say things that lower the pressure. “This is an illness, not a failing.” “You don’t have to do everything perfectly.” “I’m here.” Avoid “every new mother feels this way,” because it tells her to put up with it.
Take over specific jobs. “Can I help?” puts the work back on her. “I’ll do the night feed at 2 a.m. with pumped milk, you sleep until 6” helps. Protecting one long stretch of sleep a night makes a real difference.
Keep visitors in check. In many Indian households the postpartum period brings a stream of relatives and advice. Ask family to cook and hold the baby, not to judge.
Postpartum depression in fathers
About 1 in 10 new fathers develop depression, most often when the baby is three to six months old. In men it often shows as irritability, longer hours at work, or drinking more. The risk rises sharply if the mother is depressed.
Can Postpartum Depression Be Prevented?
Not always, but the risk can be reduced. The US Preventive Services Task Force reviewed the evidence and found that CBT or IPT counselling in pregnancy cut the chance of developing perinatal depression by 39% in women at higher risk. If you have had depression before, tell your doctor early in pregnancy and ask about a referral.
Before the birth, agree who will cover night feeds and meals for the first six weeks. Save a helpline number in your phone, and tell one person you trust what the warning signs look like. Our piece on identity changes after a baby covers feelings that are not depression but still need room.
Frequently Asked Questions
Is postpartum depression my fault? No. Hormones, sleep loss, and stress drive it. It says nothing about how much you love your baby.
Will postpartum depression affect my baby? Untreated, long-lasting depression is linked to feeding difficulties, poorer sleep, and later emotional and language delays in children. When the mother gets treatment, those effects shrink.
Will I get it again with my next baby? Between 25% and 50% of women with PPD have it again after a later birth. Plan ahead with your doctor, since preventive therapy can lower that.
Who do I talk to first? Your obstetrician, GP, or your baby’s paediatrician. In India, Tele MANAS (14416) can link you to a counsellor in your language.
