Jessica Simpson Shares New Heartwarming Photo of Son Holding His 2-Month-Old Sister

Jessica Simpson shared on social media, a picture of her son holding his little sister, and the photo is both heartwarming and adorable.

Singer, actress, and Entrepreneur, Jessica Simpson is a proud mother of three, and never gets tired of showing off her children on social media.

She posted a photo recently on Instagram of her second child and only son, Ace Knute, holding his little sister, Birdie Mae. The soon-to-be 6-year-old boy held his 2-month-old sister in a firm grip, with his mouth hung open in a joyful expression and his eyes closed.

The little girl dressed in a blue flower-pattern onesie, looked like she did not share her brother's enthusiasm, but it didn't stop the two from looking adorable.

The heartwarming picture of the siblings was captioned simply as "#BirdieMae #AceKnute" by Simpson.

Baby Bridie, since her arrival, has enjoyed limitless attention from her two older siblings. Last week, the singer-actress shared a vintage-styled picture of the newborn and her sister, Maxi Drew.

Like Ace, Maxi, dressed in blue held the little girl dressed in a white and coral outfit. With a heart-shaped emoji at the end, Simpson captioned it:

"These ladies make my heart burst with love sprinkles."

The fashion entrepreneur and her husband, Eric Johnson, welcomed Birdie in March. After the new parents, her siblings were the first to hold her.

According to "ET," 7-year-old Maxi and Ace were excited to meet their sister, and the two while waiting for her arrival made her a welcome banner that read "Welcome Birdie."

The news outlet also reported that the two did not want to leave the hospital, and in an earlier interview with Simpson last October, she said her two older children are thrilled to be a part of the birth process because they did not have the experience with each other; they are 14 months apart.

As fun and exciting as motherhood is for the "Dukes of Hazzard" actress, it has not been without criticism. According to "The Inquisitr," the mother-of-three came under fire after sharing a photo of her newborn lying with her stomach down.

Her critics pointed out that the American Academy of Pediatrics recommends that babies sleep on their backs to avoid SIDS.

Tina Simpson, the singer's mother, came to her defense. She pointed out that the position was for a photo and asked the critics to "Enjoy the preciousness."

Criticisms or not, Simpson is a good mother who is proud of her children and devotes her time to them.
