Body language expert analyzes Carrie Underwood and Mike Fisher with their newborn son

Susan Constantine, a body language expert, said Carrie Underwood and her husband Mike Fisher are truly proud parents.

The human behavioral expert and author of “The Complete Idiot’s Guide to Reading Body Language” analyzed the celebrity couple with their new baby boy, Jacob Bryan, as reported by Delish.

Underwood earlier opened up about how Isaiah feels about having a baby brother. She said that Isaiah had jealous thoughts about his then brother-to-be.

Constantine studied sweets photo of the couple with their newborn, saying there’s a lot that can be gleaned from these snapshots. She said: “The slight raise of the eyebrow says, ‘Look what I did.’ People flash their eyebrows when they’re emphasizing something.”

Jacob Bryan is Underwood and Fisher’s second baby. They have a three-year-old son Isaiah Michael.

AN EXPERIENCED FATHER

Looking at Fisher’s gesture in the photos, Constantine noted his being an experienced father.

"The fact that he's holding the baby so close to him—I mean he's got the swaddle down very well," she said. "Sometimes dads seem awkward with newborns, but he looks relaxed and at ease. The way he's embracing his baby, there's a deep sense of love there and he's comfortable being a dad. There's a lack of facial tension, and it's like he's done this a number of times before."

Susan also interpreted Underwood’s body language in the photos.

She said: "When you look at her facial expression, she has the after-baby glow, and it's so pure and innocent. There's this sense of serenity about her facial expression and she has a slight curvature in her smile. No tension—she is completely in bliss."

JEALOUS BROTHER

Underwood earlier opened up about how Isaiah feels about having a baby brother. She said that Isaiah had jealous thoughts about his then brother-to-be.

“[Isaiah] told me recently that when the new baby comes that Daddy could have that baby and then he could be mine,” she shared.

She wondered whether her upcoming child would be a “daddy’s” boy.

“Maybe this next one will be all Mike’s. Maybe that will be how it works out. Mike needs some love too. I feel bad for him sometimes,” she joked.
