Mattel Inc. on 8 July unveiled the first Barbie doll designed to represent a child living with Type 1 diabetes, expanding the 2025 Barbie Fashionistas line that focuses on diversity and inclusion. The doll features a continuous glucose monitor held in place with heart-shaped pink tape, an insulin pump attached to her waist and a smartphone displaying real-time glucose readings. It is on sale now for about $10.99 at major U.S. and U.K. retailers. Developed over nearly two years in collaboration with the research and advocacy group Breakthrough T1D, the design was vetted by people who use these medical devices daily. “Introducing a Barbie doll with Type 1 diabetes marks an important step in our commitment to inclusivity and representation,” said Krista Berger, senior vice president of Barbie and global head of dolls. Mattel also created one-of-a-kind dolls in the likeness of British model Lila Moss and Peloton instructor Robin Arzón—both of whom have Type 1 diabetes—to promote the launch. The company is donating additional dolls to delegates at the Breakthrough T1D Children’s Congress in Washington, D.C., this week. The release comes as more than 300,000 U.S. children manage Type 1 diabetes, and advocates say seeing their condition reflected in toys can help normalize medical devices and reduce stigma. The Fashionistas range now includes more than 175 dolls with varied skin tones, body types and disabilities, such as prosthetic limbs, hearing aids and Down syndrome.
