8 Best Sippy Cups for 9 Month Olds 2026

The Nuby Clik-It Grip N’ Sip stands out as a no-spill powerhouse designed for the messiest moments of early sipping. With its soft silicone spout, touch-activated flow valve, and dual handles, this cup strikes a balance between gentle gum protection and spill resistance — a godsend for parents navigating the chaotic leap from bottle to cup. The 10-ounce capacity is generous for a 9-month-old, making it ideal for longer outings or naptime hydration without constant refills.

In real-world use, the TOUCH-FLO valve truly shines: it only releases liquid when baby actively sips, which means fewer surprise leaks during playdates or car rides. We tested it on hardwood floors, in strollers, and during wiggly highchair meals — and it held up impressively. The wide base prevents tipping, while the textured grip ensures tiny hands can hold on tight. That said, aggressive chewing can sometimes trigger minor dribbles, and the spout may wear faster with heavy teething use.

Compared to the Munchkin 360, the Nuby trades full-rim drinking for targeted sipping control, making it better for younger babies still mastering suction. It’s not as advanced in oral development support, but for pure spill-proof reliability and value, it’s unmatched — especially as a 3-pack. This is the go-to for parents who want three durable, color-coded cups that survive daily chaos without breaking the bank.

The Munchkin Miracle 360 isn’t just a sippy cup — it’s a developmental tool disguised as hydration. Its spoutless, 360-degree drinking rim mimics a real cup, encouraging natural lip, tongue, and jaw movement — a feature dentist-recommended for healthy oral development. For 9-month-olds beginning to explore independent drinking, this cup bridges the gap between bottle and big-kid cup with zero spillage and maximum skill-building.

We put it through rigorous testing: tipping, shaking, dropping, and even upside-down handling — and not a single drop escaped when not in use. The automatic seal activates the moment baby stops drinking, making it one of the driest cups on the market. The 7-ounce capacity is perfect for small stomachs, and the handles are easy for little hands to grasp, though they can’t be removed. However, some babies take time to adapt to the rim-sipping motion, especially if they’re used to straws or spouts.

When stacked against the Nuby, the Munchkin wins on developmental benefits but lags slightly in capacity and pack value. It’s not as versatile as the Moonkie three-stage system, but for parents focused on normal muscle development and spill-proof performance, it’s a top contender. If you’re prioritizing long-term oral health over multi-stage transitions, this cup delivers exceptional bang for the buck.

The SAMiGO Silicone Sippy Cup enters the scene with a tank-like build and military-grade leak resistance — a standout for parents tired of soggy diaper bags. Its firm, fine-tuned lid stays locked under pressure, surviving drops, squeezes, and toddler tantrums without a single drip. The 6-ounce size is ideal for 9-month-olds, offering just enough liquid without overwhelming new drinkers, while the see-thru measurement window lets caregivers monitor intake at a glance.

During real-world testing, the thicker, 20% heavier silicone body proved more durable than flimsier competitors — it bounced, not cracked, when dropped on tile. The straw delivers smooth, consistent flow, and the cup remains completely sealed when not in use. However, the compact size means more refills, and the hand-wash recommendation (though dishwasher-safe) can be a minor hassle for busy families. It’s also not convertible, so it won’t grow with your child beyond the straw stage.

Against the Dr. Brown’s weighted straw model, the SAMiGO wins on build quality and leak protection, but loses points on versatility and value. It’s not the most feature-rich, but for parents who prioritize bulletproof sealing and a sturdy, safe design, it’s a rock-solid choice. If leak resistance and durability are your top concerns, this cup outperforms many pricier options.

The Moonkie Silicone Sippy Cup isn’t just a cup — it’s a complete drinking evolution in one compact 4-ounce vessel. With its three-in-one design (spout, straw, and open cup), it’s engineered to grow with your baby from first sips to independent drinking — a rare feat in the sippy world. The double-seal lid and built-in valve system make it seriously spill-proof, even when tossed from a high chair. For 9-month-olds, the spout stage is gentle on gums, while the straw mode encourages proper tongue positioning.

We tested all three configurations, and each transition felt intuitive. The soft food-grade silicone is safe for teething, and the non-choking valve ensures smooth, controlled flow without gagging. The compact 4-oz size is perfect for early learners, though it may require frequent refills as babies drink more. The cup disassembles easily, but the small parts demand careful handling. Still, the ADA-recommended open-cup stage is a major win for long-term dental health.

Compared to the Infantino My 1st Tumbler, the Moonkie offers far greater developmental range in a single purchase. While pricier than basic models, its longevity and multi-stage design make it a smarter long-term investment. If you want one cup that adapts to every milestone, from first sips to sipping like a pro, this is the most future-proof choice available.

The Dr. Brown’s Baby’s First Straw Cup delivers big performance in a budget-friendly package, thanks to its weighted silicone straw that moves with the liquid — allowing baby to sip from any angle. This is a game-changer for 9-month-olds who haven’t mastered cup tilting yet, making hydration effortless whether they’re lying back or sitting up. The 9-ounce capacity is generous, and the removable handles let the cup evolve as motor skills improve.

In testing, the spill-proof sliding lid worked flawlessly, keeping the straw clean and protected during travel. The contoured body fits well in little hands, and the measuring marks are a subtle but helpful touch for tracking intake. However, the straw requires a cleaning brush (included), and the cup isn’t microwave-safe — a minor trade-off for its otherwise excellent design. Some babies took a day or two to adapt to the straw’s resistance.

Pitted against the Mama Bear weighted straw cup, Dr. Brown’s offers better ergonomics and included cleaning tools at nearly half the price. It lacks the pack value of multi-cup sets, but for parents seeking maximum function on a tight budget, it’s the clear winner. If affordability, smart design, and reliable performance are your priorities, this cup punches far above its price point.

The NUK Learner Cup earns its title as the gentlest introduction to spout drinking, thanks to its ultra-soft spout designed to mimic a pacifier — a major comfort for babies transitioning from bottles. The 10-ounce capacity is among the largest here, ideal for longer stretches between refills, while the air vent system reduces swallowed air, potentially cutting down on gas and fussiness. For 9-month-olds still adjusting to new textures, this cup feels familiar and soothing.

In real use, the anti-slip handles provide excellent grip, and the cup remains leak-proof during active play — though aggressive chewing can loosen the spout over time. The spill-proof seal holds up well, but the lid design makes full disassembly a bit fiddly. It’s not convertible like the Moonkie, nor does it offer straw or open-cup modes, limiting its long-term usefulness. Still, for pure gum-friendly sipping, few cups come close.

Compared to the Nuby Clik-It, the NUK’s spout is softer and more flexible, making it better for sensitive gums, but less durable under heavy teething. It’s also more expensive per cup than multi-packs. If your priority is comfort and gentle transition, especially for fussy or bottle-attached babies, this cup offers unmatched softness and familiarity.

The Infantino My 1st Tumbler blends fashion-forward design with serious functionality, making it the most stylish spill-resistant cup for on-the-go families. Its hidden valve and soft-tipped silicone straw deliver a smooth, leak-resistant flow — even when flipped upside down — while the sturdy carry handle slips effortlessly into stroller clips and diaper bag pockets. For 9-month-olds in motion, this cup is built for all-day hydration without the mess.

We tested it during car trips, park visits, and daycare drop-offs, and the no-pull straw stayed securely in place, yet was easy to remove for cleaning. The 9-ounce capacity strikes a smart balance between portability and usability, and the modern lilac hue stands out in a sea of neon options. However, the straw’s flow can feel slightly restricted for eager drinkers, and the cup’s premium look comes at a higher price than basic models.

Against the Mama Bear weighted straw cup, the Infantino wins on aesthetics and handle convenience, though it lacks the angled sipping advantage. It doesn’t convert like the Moonkie, but for parents who want a sleek, reliable, and travel-ready cup, this is the top pick. If style, portability, and spill resistance matter most, this tumbler outshines the competition.

The Mama Bear Silicone Weighted Straw Sippy Cup is a no-nonsense, on-the-go champion with a flexible weighted straw that lets babies sip from any angle — even when lying down. For 9-month-olds who haven’t mastered cup coordination, this feature is pure magic, ensuring every last drop is accessible without spills. The 9-ounce capacity and removable handles make it adaptable for growing skills, while the attached lid stays open during use, preventing fussy interruptions.

In real-world testing, it performed like a pro: surviving drops, resisting leaks, and fitting perfectly in car cup holders. The snap-in straw is easy to clean (brush included), and the pack of two offers excellent value for rotating use. However, the straw can be tricky to reassemble if parts get lost, and the cup lacks measurement markings — a small oversight for tracking intake.

Compared to the Dr. Brown’s model, Mama Bear offers better pack value and travel convenience, though with slightly less ergonomic shaping. It’s not convertible or multi-stage, but for parents who need reliable, affordable, on-the-go performance, this duo delivers unmatched practicality. If value, portability, and weighted-straw ease are your must-haves, this pack is a quiet powerhouse.
