Jessica Simpson Shares Adorable New Photo of Baby Daughter Birdie Mae: 'Rollin' Into the Weekend'

Jessica Simpson is showing off her baby girl!

On Friday, the singer-turned-lifestyle-entrepreneur, 38, shared another adorable photo of her daughter Birdie Mae, 5 weeks, to Instagram.

In the black-and-white image, Birdie lays on her back, wearing a patterned sundress, and flashes a tiny smile while staring up at the camera.

To make things even cuter, the baby holds her hand to her chin, which displays her adorably-chubby arms and cheeks.

“Rollin’ into the weekend #BIRDIEMAE,” Simpson captioned the cute snap.

The newest photo of Birdie comes nearly one week after Simpson celebrated Easter with her family and shared a photo — the first to feature all three of the star’s children — wearing their coordinating holiday outfits.

“Happy Easter from the Johnson Family, Party of 5!” she captioned the sweet photo, adding several festive Easter emojis.

In addition to the family photo, Simpson also showed off a new close-up image of her youngest daughter, who appeared to be taking a nap on her belly, while wearing her floral dress and matching white headband.

“Birdie Mae Johnson,” Simpson simply captioned the snap.

The following day, the new mom of three shared her happy news with the world, posting a black-and-white photo of her daughter Maxwell “Maxi” Drew, 6½, meeting the newest addition to the family.

“We are so happy and proud to announce the birth of our perfect daughter, Birdie Mae Johnson,” Simpson captioned the sweet shot. (She and the former NFL player also share son Ace Knute, 5½.)

Shortly after baby Birdie’s arrival, a source told PEOPLE that Simpson couldn’t be happier with her family of five.

“Jessica is feeling good. The baby is doing really well,” the source said in March. “Birdie is perfect and Jessica is savoring every minute. They are elated. They are just soaking it all in.”

Maxwell and Ace “are so excited” and “can’t get enough of” their new baby sister, the source added.

Though Simpson has been in total bliss since welcoming her daughter, she has admitted to facing some difficulties as a new mother of three.

“Three is challenging. We are trying to get into the groove and make sure all three kids are getting equal attention … it’s more than a full-time job right now,” she recently told PEOPLE.

“The other night, all three kids were crying at the same time, so I just joined in! Ha!” Simpson joked.

Despite those challenges, Simpson said she wouldn’t have it any other way.

“[Birdie] makes our family complete,” she explained. “Someone once told me to keep in mind that everything is a phase with infants and kids … trying to remember that fact, and celebrate the small victories.”

“We are trying our best to be as present as possible and enjoy every part of having a newborn,” Simpson added. “We know how fast the time goes and how precious it is.”
