“Happy Easter from the Johnson Family, Party of 5!” she wrote.

Simpson and her husband, Eric Johnson, welcomed Birdie on March 19. “We are so happy and proud to announce the birth of our perfect daughter, Birdie Mae Johnson,” she said at the time.

“[Birdie] makes our family complete,” Simpson told People magazine. “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,” she added. “We know how fast the time goes and how precious it is.”
