Postnatal depression can last for months, or sometimes years, after a baby is born. Exactly how long it lasts varies from person to person, depending on individual circumstances. 

Postnatal depression and anxiety generally get better with time; however, these conditions are very treatable and women who seek generally get better faster. 

Although it’s normal to experience symptoms of depression and anxiety every now and then (especially after having a baby), if you’ve had signs of depression or anxiety for more than 2 weeks, then you could benefit from having a check-in with your doctor. 

Postnatal depression typically begins a few weeks or months after birth. However, the term ‘postnatal’ can refer to up to two years after a baby is born, and it’s not uncommon for women to develop postnatal depression symptoms a year or so after giving birth. 

Postnatal depression isn’t normally diagnosed within the month after birth, as this is an adjustment period where it’s very normal to be feeling tired and irritable. 

There’s no set formula that can identify exactly who will develop postnatal depression and anxiety. There are some common risk factors, including: 

  • Having a history of anxiety, depression, or other mental health issues 
  • Having problems with drugs and alcohol 
  • Having a complicated or traumatic pregnancy or birth 
  • Your baby having health difficulties or complications during pregnancy or after birth 
  • Experiencing very stressful situations (e.g. divorce, losing your job, domestic violence) during pregnancy or birth 
  • Having limited social support 

However, not everyone with these risk factors will develop postnatal depression, and some people will develop postnatal depression due to other circumstances. 

Overall, although this condition is common, most women who have a baby won’t develop postnatal depression.
