WATCH: Sexy mother slaps her 1-day-old baby

Before you get mad at her, know the reason behind the behavior of the sexy mom who was caught slapping her own baby a day after giving birth.

The unidentified mother delivered her baby at the Pasay City General Hospital on August 18. The following day, she was captured on camera hurting the child. The video immediately went viral via social media.

ABS-CBN News reported that some personnel of the city's social welfare and development office already separated the child and the mother, who was scheduled to undergo a psychological assessment.

According to CSWD officer Rosalinda Orobia, the mother is suffering from a postpartum depression (PPD), a type of clinical depression which affects new moms after childbirth.

The symptoms of PPD (also called postnatal depression) include sadness, irritability, anxiety, and crying episodes.

Once proven that the mother is mentally ill, her transfer to the National Center for Mental Health would be recommended, the report said.

The CSWDO is also looking into the possibility of bringing the newborn to their relatives after it was found out that the woman's live-in partner is not the baby's real father. If no relatives are willing to take care of the baby, Orobia said they will bring the child to an institution.
