Mom Hilary Duff – who has been Tweeting out what seems like every significant moment of her son's life – recently shared that the little guy is now teething.
"Luca is cutting a tooth!!!" Duff Tweeted last Thursday. "It's the cutest/saddest (because it hurts) getting so big my boy!! Gunna have a little toof lol."
Duff, 24, also Tweeted a pic of Luca munching on a "Tasty toy" earlier this month, during what appeared to be his pre-teething stage.
But Luca isn't the only Duff family member experiencing a major milestone: Deadline reports that Duff recently signed a deal with 20th Century Fox TV to develop a half-hour comedy for which she will star on and produce. Duff confirmed the news on Twitter Monday – but only after sharing yet another adorable pic of Luca.
"OK it's official!" she wrote. "Very excited about my development deal with 20th century fox!! t.v. here I come! :)"
