BrightKidCo is a US potty-training brand offering reusable training underwear and gentle daily fiber support for children. Its underwear is designed to help children notice the feeling of needing the potty while providing some leak resistance. The everyday range is intended for children ages 2–5 and features a Body-Signal Learning Layer, a 100% cotton inner layer described as OEKO-TEX certified, and a washable, reusable design.

BrightKidCo also offers a separate Autism and Sensory Edition, developed with occupational therapists and neurodivergent parents. These training pants use the same learning layer with a gentler design, including tag-free construction, flat seams, and quiet fabric for sensory-sensitive children. The company sells the underwear in sets of four pairs and offers a 100-day money-back guarantee tied to visible progress in recognizing body signals.

Its Happy Poop Gummies provide daily fiber and prebiotic support for children who find bowel movements difficult or stressful. Customers can shop the training pants, gummies, and other products through the BrightKidCo website, which also provides FAQs and customer support.
