The actress, 43, wished her son Tennessee a happy seventh birthday on Thursday with a few sweet Instagram posts.

“Boy, this kid makes me laugh! Happy 7th birthday to my sweet boy Tennessee,” theBig Little Liesstar wrote in a caption underneath aphotoof the mother/son pair. “Here’s to a day filled with chocolate cake, Beyblades and dog cuddles! 🎈#thisis7.”

On herInstagram Stories, Witherspoon shared some fun moments from Tennessee’s special day.

She shared a video of birthday decorations, including a large gold “7” balloon and “happy” garland. Then she showed off what Tennessee is loving these days: “lots of hexbugs” and “so many beyblades!”

TheMorning Showactress shares Tennessee with husbandJim Toth, and her two older kids, Ava, 19, and Deacon, 15, with ex-husbandRyan Phillippe, and the star loves to share her adventures in parenthood with her fans and followers online.

The Draper James founder explained in another Instagram post in late August that she communicates with her three kids on Snapchat, featuring asilly selfie, in which she looks shocked with a Snapchat filter over her face.

“Are you seriously telling me TODAY about all the school supplies you need tomorrow?” she wrote atop the photo. In the caption, she added, “How to talk to your kids on snapchat… the filter adds a much more serious tone, don’t you think? 📚 #momlife #backtoschool.”

But Witherspoon can’t juggle her many projects and three kids without a little help from a very relatable source.

“Coming to you this Thursday to remind y’all that behind every successful woman is a strong cup of coffee and a pair of practical ( and cute 😉)shoes. ☕️👟,” she wrote in anInstagram captionfor a photo from the set ofLittle Fires Everywhere, in which she stars oppositeKerry Washington.

In the photo, she holds up a cup of coffee while reading a script on the ABC Studios lot. She added in the caption: “*not sponsored but accepting all coffee endorsement offers.”
