Perfect Cups For 6-18 Months: Moonkie's straw cup is the ideal transition for your little ones to wean from the bottle. Our set is designed to encourage a smooth transition to independent drinking, from bottle to cup. The sturdy design is not just about preventing spills but also gives your little explorer a good grip, reducing the chances of tipping and making sipping simple! Of course, these cups are versatile: use it with a lid at first and without the lid when your kiddo is ready. Silicone Straws with Stoppers and Covers: Our built-in straw stoppers prevent your little one from pulling their straw out, making mealtime that much easier for parents. With the handy straw cover, parents can keep the straw clean and hygienic when not in use, making it a win-win for both convenience and cleanliness. Clear Silicone sippy cup Design: Parents can see exactly how much is left and what their baby is sipping without popping the lid. Plus, when it's cleanup time, the see-through design makes it super easy to spot any leftover liquid, making cleaning a breeze. Drop Proof and Spill Proof: Our straw cup features a double-seal design, ensuring a secure closure even if it takes a tumble. One of the two straws we provide you comes with a built-in valve to prevent spills and slow the flow. The other straw is a step up in flow for easy sipping. As your baby explores, feel confident and at ease knowing our straw cup can handle their fussy moments across multiple stages. Food Grade and Toddler-Tested Silicone: Our sippy cups with straw is made from 100% food-grade silicone, free of BPA, PVC, phthalates. These straw cups are gentle on developing teeth and gums, yet sturdy enough to withstand toddlers! And it’s 100% dishwasher safe for quick and easy cleanup!
