When we were little middle-class white kids in the 50s-60s, we were sent to “cotillion” classes organized in our neighborhood for kids aged 11-13. Lots of communities had these etiquette classes for boys and girls before the onset of school dances and dating.
One of my choir members (Rafaela, the six-foot tall goddess from Acapulco) teaches children and teens to dance for their social events. When they have the party to celebrate a child’s “Presentation,” at the 3rd birthday, the older siblings will do something like a minuet. At a Quinceanera, the birthday girl and her siblings and friends will do several dances.
Cotillion is still a thing in the South. http://nljc.com/nljc/index.php?p=chapters&a=county&state=Virginia&county=Northern%20Virginia
