“Amber spent almost her whole pregnant feeling sick — not just the first trimester, and not just in the mornings,” a source close to the 27-year-old Teen Mom OG star tells PEOPLE.
“She was sick day and night. It was brutal,” the source explains.
An insider confirmed to PEOPLE on Tuesday that Portwood had welcomed her son, James, with boyfriend and cinematographer Andrew Glennon. (Portwood and Glennon met on the set of Marriage Boot Camp: Family Edition last year.)
“Baby James is here and Amber is over the moon,” said the insider, adding that the newborn weighed 7 lbs., 11 ounces, and was born at 1:39 a.m.

Although each pregnancy is different for every woman, Portwood’s sickness wasn’t a surprise to the mother of two, who also battled months of ill feelings when she was carrying her firstborn: 9-year-old daughter Leah, whom she shares with ex Gary Shirley.
“It was the same problem she had in her first pregnancy, she was just sick all the time,” the source says.

Despite her morning sickness, Portwood is happy to be building a life with her boyfriend as a family of four.
“In spite of all that she was just so happy to be starting over with a guy like Andrew,” the source says. “And now that the baby is here, they are over the moon.”
Not long after the MTV personality gave birth to her son, the mother of two shared a sweet photo to Facebook of herself holding the adorable infant in the hospital. A day later, she also posted a snap of Leah smiling and holding a swaddled baby James.
“Big Sis and little James! She was so excited to meet her little brother,” Portwood captioned the photo.
