For the first few months after Cairo was born, she developed intense feelings that she hid from her doctor, such as crying all the time and having thoughts like worrying her daughter would be smothered overnight, she told Romper. "When I knew that I had postpartum [depression] … I didn't want to admit it. It was that shame," she said. But she did eventually tell her husband, friends and twin sister. "They became my support system. So when I was sad or going through my emotions, I would talk about it. I didn't suppress them. I think that helped," said Mowry-Hardrict, adding that she started to feel like her normal self by the time Cairo was 6 months old. Another thing that helped, according to the star, was going back to work: "Just being on set and it not being about your boobs and a baby, it was about you again."
