Baby Riley was rushed to the neonatal intensive care unit after his arrival.
Trainor is opening up for the first time about her emotional and scary birth experience. In a recent interview, Trainor says, "It was one of those horror stories where he didn't cry. He didn't make noise when he came out. I was like, 'Why isn't he crying?' Then they told me he was having breathing issues. It was terrifying."
"I got to see him for one second before they took him away. That was probably the worst part," Trainor shared. "It was definitely a rough start. But we're so lucky we got to bring him home after five days."
Thankfully, 3-month-old Riley is now perfectly healthy and doing great.
Trainor is sharing a beautiful roundup of baby photos and videos, set to her new cover of "If You Love Her" with Forest Blakk, on her Instagram.
The new mama and Grammy-winning singer, who has been open about her struggles with anxiety and depression, also revealed that she stayed on a low dose antidepressant throughout her pregnancy.
"I made sure it was safe and talked to my doctors," Trainor shared. "They told me, 'If you're happy, then your body will be happy and then your baby will happy.' I haven't had any postpartum depression or anything. I think the medicine definitely helped."
Trainor also attributes her positive mental state to therapy, her "amazing" family and exercise as she navigates the early days of motherhood.
And just like every new mama, Trainor says, "I'm biased, but he's the smiliest, happiest baby."
