Mattel has released the first Barbie® doll with type 1 diabetes, developed in partnership with Breakthrough T1D (formerly JDRF).
The doll includes a continuous glucose monitor (CGM) on the upper arm and an insulin pump at the waist—devices modeled after current type 1 diabetes (T1D) management tools. She also carries a small purse designed to hold diabetes supplies or snacks.
Breakthrough T1D reviewed the design for clinical accuracy. “I have lived with T1D since I was 13, and my brother since he was 3, so this partnership is deeply personal,” said Aaron J. Kowalski, PhD, chief executive officer of Breakthrough T1D. “It’s an honor to work with a brand that shares our commitment to showing children that a life with T1D can be full, vibrant, and empowering.”
The launch coincided with the 2025 Breakthrough T1D Children’s Congress, where Mattel donated dolls to 170 youth delegates. Barbie also created custom dolls for two public advocates—Peloton instructor Robin Arzón and model Lila Moss, both living with T1D.
The doll is part of the Barbie Fashionistas line, which has previously featured models with disabilities and chronic conditions. According to Mattel, all 2025 Barbie Fashionistas are produced using at least 50% ISCC-certified bio-circular plastic. The T1D Barbie is available via Mattel’s website and retail stores.
