Lin-Manuel and Vanessa's first child, a son named Sebastian, was born on Nov. 10, 2014. Lin-Manuel announced his son's birth on Twitter with a photo of the newborn and the very fitting-for-a-playwright caption: "[The screams reach a frenzied pitch. SEBASTIAN MIRANDA enters. He is 7 pounds 10 ounces.]" So adorable!
Sebastian seems to be a budding filmmaker and actor, according to Lin, who shared in a tweet that every weekend he acts as cinematographer for his son's movies. "And while I can't show you clips because he and his brother are the stars, I have permission to post this exclusive pic of my brother-in-law Tristan as an elephant," he wrote alongside a photo of Tristan in a handmade elephant mask.
In September, Lin celebrated Sebastian's first lost tooth and turned to his followers to ask the going rate for the Tooth Fairy these days — $1 for a first tooth, according to a Twitter poll. "BREAKING: We got a first lost tooth here, I repeat, the five year old lost a tooth, pretty sure it is ALSO the first tooth he ever got," Lin wrote, adding in another tweet: "The five year old BOUNDED in at 1am with a crisp bill covered in a magical glitter only known to tooth fairies and pharmacies open late on Tuesday evenings. Also included: a receipt of sale filled out in a cursive that looks NOTHING like [Vanessa]'s handwriting. Thank you all."
