I would be the last person to volunteer to go up on stage and dance or sing in front of a room full of people (or iPhone screens which presumably have people holding them up,) so I’ve had some challenges convincing my kids to get excited about things like recitals and school plays.
“You’ll be great!”
“There’s nothing to be afraid of!”
“No one has ever literally died of embarrassment (that I know of) so PLEASE JUST PUT ON YOUR DAMN BALLET SHOES!!”
If parenting has taught me nothing else, it’s that it’s impossible to be rational with irrational little humans, especially when their fear is actually pretty rational and natural, (and your primary driver for making them perform is the fact that you just shelled out $50 for that recital costume, so it will be worn on stage even if you have to go up there and move your child’s limbs like a little, angry marionette.)
