  • NIMH says most episodes begin 4 to 8 weeks after birth.[1]
  • OWH says postpartum depression usually starts within the first month.[2]
  • MedlinePlus says it can begin at any time in the first year.[4]
  • ACOG says postpartum depression can occur up to 1 year after birth, and most commonly starts about 1 to 3 weeks after.[3]

Signs to watch for

NIMH lists these symptoms, lasting at least 2 weeks:[1]

  • sadness or a feeling of emptiness;[1]
  • loss of interest in things;[1]
  • guilt;[1]
  • changes in sleep and appetite;[1]
  • trouble bonding with the baby;[1]
  • thoughts of harming yourself or the baby.[1]

MedlinePlus says extreme sadness, or being unable to care for yourself or your baby, may be postpartum depression.[5]

How common it is

CDC survey data show that about 1 in 8 women with a recent live birth reported symptoms of postpartum depression.[6]

What can raise the risk

MedlinePlus lists a personal or family history of depression or bipolar disorder, problems during pregnancy or birth, a baby with special needs, domestic violence, money stress and little support.[4]

The Office on Women's Health (OWH) lists little or no support from family, friends or partners.[2]

Treatment

NIMH says treatment is usually therapy, such as cognitive behavioral therapy or interpersonal therapy, medicine, or both.[1]

MedlinePlus says treatment includes antidepressants and talk therapy.[4] It says people who are breastfeeding should tell their provider, so options can be chosen with that in mind.[4]

ACOG says to call your ob-gyn right away if you think you may have postpartum depression, or if your partner or family are worried, and not to wait for the postpartum checkup.[3]

Rest, support and checkups

OWH says to rest as much as you can and to sleep when the baby is sleeping.[2]

MedlinePlus also recommends getting as much rest as possible after birth.[5]

OWH describes ways partners and family can help:[2]

  • caring for the baby so the mother can rest;[2]
  • doing household tasks;[2]
  • listening;[2]
  • making calls for her.[2]
