Sarah opened up in February about Charlotte, telling E! that she has been helping Charlotte navigate the teenager world, especially social media.

"I can't stop Charlotte, but I can teach her," she said of allowing her daughter on the internet. "I can teach her why not to look at that website, or not to believe everything that you see or maybe take a break from the Snap map."

"My daughter is a competitive dancer,” the Scooby Doo actress continued. "She dances five days a week. The girls are such a team, and they all support each other."

Along with Charlotte, Freddie and Sarah share son Rocky James, who celebrates his birthday this week as well. On Friday, SMG shared another post celebrating his 12th, using a throwback photo.

"Raise your hand if it’s your birthday!!! 12 years ago, Charlotte told us all she wanted for her third bday was you," Gellar captioned the post. "And even though you weren't due for another three weeks, she got her wish… and we all got the greatest gift. You. Happy birthday Rocky!!!! 🎉🎉🎉🎁🎁🎁🎂🎂🎂"
