The Infantino My 1st Tumbler is a baby-friendly silicone sippy cup that looks just like Mom’s favorite tumbler – only perfectly sized for little hands. With a soft, flexible design and 9oz capacity, it’s made to help babies build sipping skills while feeling just like the grown-ups. Crafted from 100% food-grade, BPA-free silicone, this tumbler features a sturdy handle and a soft straw with an internal valve that allows smooth sipping and helps prevent spills – even when turned upside down. The no-pull-out straw stays secure for baby but comes apart easily for parents to clean. Perfect for water, milk, or juice, this baby tumbler fits most stroller and car seat cup holders and packs easily into a diaper bag. Dishwasher safe and made for everyday use, it’s a stylish, smart essential for keeping little ones hydrated wherever the day takes you.
