Happy Birthday, Tennessee!

It was a family affair for Tennesee Toth on Monday as he celebrated his fourth birthday with mom, Reese Witherspoon, dad, Jim Toth, and his two look-alike half siblings, 17-year-old Ava Phillippe and 12-year-old Deacon Phillippe.

Tennessee’s big day was, of course, well documented by his famous multi-tasking mom.

Witherspoon was eager to share, posting a photo of Tennessee’s personalized Teenage Mutant Ninja Turtles cake—complete with a colorful trail of Skittles:

The proud mama followed up with a solo pic of the birthday boy in tiny yellow sweat pants, smiling as he held the string of a red balloon:

Witherspoon concluded the photo account with a shot of the whole family celebrating alongside a joyous Tennessee.

Reese’s kids all look so grownup! Pre-teen Deacon appears to be rocking a hip side-cut in the photo, while Ava looks totally music-festival-chic in a set of French braids and an on-trend choker. Matriarch Witherspoon looks charming as always standing between her kids in a gray flannel shirt.
