The Rosie Bee Silicone Square Stacking Cups bring a fresh twist to classic developmental toys. Made from 100% food-grade silicone that’s free of BPA, lead, and phthalates, these colorful cups are safe for teething babies and curious toddlers alike. They pass the pinch test, meaning no fillers or impurities—just pure, chewable silicone that parents can trust.
What sets these apart from traditional wooden stackers is their versatility. Take them to the bath, pool, or beach without worry. They’re waterproof, easy to clean (handwash, top-rack dishwasher, or boil), and built to last through years of play. Start using them as teethers when your baby is young, then transition to stacking, nesting, and sorting as they grow. This longevity makes them a smart investment for developing fine motor skills, problem-solving abilities, color recognition, and cause-and-effect understanding.
Who Is This For?
These stacking cups work beautifully for babies around 6 months who are teething and need something safe to gnaw on. As your child grows into the toddler years, the cups become an engaging Montessori-inspired toy for building, sorting, and imaginative play. Parents who want screen-free activities, caregivers looking for bath toys that actually serve a purpose, and anyone seeking durable, non-toxic toys will appreciate what Rosie Bee offers. The included storage bag makes them travel-friendly too.
Bottom Line
Rosie Bee delivers a thoughtfully designed toy that grows with your child. The square shape adds a unique stacking challenge compared to round cups, and the silicone construction means they’ll survive whatever your little one throws at them—literally. Created by a small Arizona family business inspired by their daughters, these cups combine safety, durability, and developmental benefits in one colorful package. If you want a toy that transitions from teether to learning tool while standing up to water play and daily use, these stacking cups are worth considering.
