She took most of the first act to grasp exactly what Angelina, her mischievous friend Henry and the other mouselings were doing up their on stage.
"Are there people in the costumes," she asked.
Yes, hun, they are dancers.
"But are there real people in the costumes," she asked again.
It made me wonder if we should give her and younger her sister more treats of this sort. Well, for a minute at least, because who can afford it? I'm afraid they will mostly have to be content with their jungle gym in the backyard.
However, on Angelina day I reckon I got more cuddles from Mia in one day than any other day since she was born. She kept coming up and giving me sporadic hugs of the brief but tight gripping kind.
To use a phrase my mum still quite likes: she was tickled pink with the show.
I always fancied myself as a soccer dad. Or some other sort of sporting dad. But if Angelina, or even Giselle and Sleeping Beauty, get this sort of result, then I'll take being a ballet dad any day.
And yes, she jabbered most of the way through the performance, but at least she wasn't the girl who groaned at the top of her voice that "I can't believe how boring this show is" during one of Angelina's poignant dream sequences.
My Mia was a little angel - even though I know she is prone to outbursts of whining, grizzling, and insolence, just like they all are.
