Hi, Melissa!
Thanks for visiting the Disney Parks Moms Panel with your question. A Bibbidi Bobbidi Boutique makeover would be a fun way to pamper your older princess during your visit with the help of a Fairy Godmother-in-training and her magic wand!
It’s important that children do meet the minimum age requirement for this experience for multiple reasons, but especially to ensure they are mature enough to sit patiently through the entire session, which takes a minimum of 30-45 minutes depending on the package chosen. Waiting until your younger daughter is at least 3 years old helps guarantee she will have a positive experience. Also, some of the makeup, styling products, costumes and accessories used are intended for girls who are age 3 and up only.
If you’d like to plan a special experience for your youngest while your oldest daughter enjoys Bibbidi Bobbidi Boutique, a visit to Harmony Barber Shop might be a fun alternative. They offer haircuts for Guests of all ages (including a special first haircut package), or she can just get a sprinkling of pixie dust! Reservations are recommended and can be made by calling (407) WDW-PLAY or (407) 939-7529, but walk-ins are also welcome depending on availability.
I hope this helps, Melissa, and that you have a wonderfully pixie-dusted visit to Walt Disney World with your family!
Wishing you magic,
Courtney
