Hi, Kathleen! The Bibbidi Bobbidi Boutique does have a strict minimum age requirement of three years old, and they are unable to make exceptions to that rule. They also do not do mini makeovers for younger children at the boutique.
You will find right outside the boutique that you can purchase pretty much everything you might need to do your own mini-makeover. All of the costumes used in the shop are there, as well as hair accessories, shoes, and things like magic wands. Pick up what you need, and you can treat her to a Mommy makeover back at your resort room.
Another option might be a visit to the
Harmony Barber Shop. A real working barber shop right on Main Street, USA in the Magic Kingdom, you can get her a little trim and a pony tail, and they will add a bit of pixie dust to make her feel like the princess she is!
Have a wonderful visit.
