The postpartum (also called postnatal) period is the time after the birth of a baby. During this time many women will experience a feeling of slight sadness or anxiety. This is called the “baby blues”, and in some women it may develop into postpartum depression. The baby blues happen in the days just after the birth and usually only last for about a day or up to a week.
Postpartum depression can occur days or months after the baby’s birth and the feelings of sadness are worse than with the blues.
