Such a big girl!

Mom-of-two Jessica Simpson posted a photo of 5-year-old daughter Maxwell on her first day of school. “Kindergarten #MaxiDrew,” the proud mama, 37, captioned the sweet snapshot via Instagram.

And she recently posted a photo of her 4-year-old son Ace preparing for preschool.

“Taking his summer break seriously #PreKHereWeCome #ACEKNUTE,” the singer-turned-entrepreneur captioned the image of her son practicing his numbers.

Last month, the mom-of-two shared a snapshot of her kids under forts and blankets while watching Moana.

In July, the proud mama shared a sweet snapshot of her smiley kids.

Simpson and husband Eric Johnson recently celebrated their son Ace’s 4th birthday with a Moana-themed party.
