"These are great - they're perfect for baby's small hands and I can attach them to tethers so they don't fall to the ground if we're out and about. The different shapes have different style ridges for teething relief. "
"My son LOVES these cups! He can't really stack them yet (9 months), but he loves knocking them over and throwing them all around. Also- they're nesting so the take up very little space when traveling."
