Minimum age to see Once On This Island?

Quick question. I have a niece who is 7 years old. Normally on the show's website it will list an age recommendation but I couldn't find any on Once on this Island's FAQ section on its website. I know there are kids in the show but what would you suggest is a minimum age to see the show?

I know for FROZEN the musical they recommend the child to be at least 8 years old. For Aladdin the musical, they recommend the child to be at least 6 years old.

Telecharge says: "Might not be suitable for children under 10 years of age. Children under the age of 4 are not permitted in the theatre."

(Caveat: I haven't seen this production yet, but I know the show itself well.) I think a 7-year-old would really enjoy it! The show is literally about entertaining a child by sharing the island's history. I don't think a typical 7-year-old would be scared by the storms or Papa Ge, though heads up that there are some general "adult themes" of wives vs. mistresses and the questionably sexist/dated message of a woman giving up everything to win the love of a man. (I mean, tale as old as time, but still.) Aside from that, the music is fantastic and catchy, and I've heard nothing but great things about this production. She'd probably love seeing the little girl(s) on stage.

^I saw this production tonight, and I completely agree. There are a lot of dark themes, a suggested sex scene, and some moments I would define as more startling than scary. I'd say it's appropriate for 11 (middle school) or so and up.
