"Hamilton" creator Lin-Manuel Miranda says his son "liked" seeing the critically-acclaimed musical.
"In advance of his 3rd birthday, we look lil man to Act One of Hamilton on Saturday. His comments in this thread..." he captioned a photo of Sebastian, who turns three Nov. 10, onstage.
Miranda subsequently shared his son's reactions to various parts of the musical, including seeing actress Elizabeth Judd portray Angelica Schuyler.
"Alexander Hamilton: 'those stairs need to COME DOWN.' He was very concerned the stairs would not come down. Whew!" the composer tweeted.
"The Schuyler Sisters: total DELIGHT in seeing @elizjudd as Angelica, with whom he has played in the park several times," he added.
"At the climax of Meet Me Inside: 'WHY ARE THEY BOTH WEARING SHOES?' (Maybe because we don't wear shoes inside? I dunno)," the star mused.
Miranda said Sebastian overall enjoyed the production, which won 12 awards at the 2016 Tonys, including Best Musical and Best Original Score.
"In summary, he liked it. His favorite part? 'The scary parts.' (Yorktown) But also 'the kissing and the fighting and singing.' Thank you," he wrote.
Miranda shares Sebastian with wife Vanessa Nadal, whom he married in 2010.
