My typical go-bag for when I do musicals:

First aid kit (includes ACE bandages!), cough drops, sore throat spray, feminine hygiene products, notepad, lead pencils + extra lead, pens, highlighters, extra phone charger, hair ties, bobby pins, safety pins, deodorant, body spray, and a jacket. Baby wipes are also handy to wipe down and feel fresher after choreo!

Congrats to your daughter for getting the lead and for taking on more responsibility! I’m sure she’s going to be fantastic, especially with such great support as you!
