Jessica Simpson publishes a photo for the start of school with all three children

Jessica SimpsonThe children will grow up and she will always love them.

The 44-year-old designer celebrated the first day of school for her three children – daughter Maxwell12, son As11, and daughter Little Bird5, which she shares with her husband Eric Johnson– on September 4th with a heartfelt tribute and rare photos of all three together.

“You make your mom shine with smiles and grace,” the “Public Affair” singer captioned her Instagram carousel, which began with a photo of the broadly smiling mother with her trio. “Continue to show yourselves every step of this new school year!”

She enthused: “I am so proud of all of you for letting your individual light shine. So that in return, others can also feel the glow.”

Jessica and her children were all pictured smiling together before striking various silly poses in the following photos of her post. In one snap, her two eldest children, Maxwell and Ace, adorably lift their younger sister Birdie into the air.
