8 Best Sippy Cups for 6 Month Olds 2026

This no-frills powerhouse delivers where it counts—smooth transitions and gum-friendly design. The soft spout mimics the feel of a bottle nipple, making it ideal for babies just starting to sip, while the removable anti-slip handles give parents control over developmental progression. With a built-in air vent to minimize gas, this cup directly tackles one of the most common feeding frustrations: colic from swallowed air. It’s a smart, science-backed upgrade from the bottle that doesn’t overwhelm tiny hands or sensitive gums.

In real-world use, the 5-ounce capacity strikes a sweet balance—large enough for a feeding session, small enough to prevent waste or spills. The Tritan material is impressively clear and resistant to stains, even after repeated use with juice or formula. We tested it on carpet, tile, and highchair trays—thanks to the spill-proof valve, it held firm every time. That said, the straw-free design means it’s best suited for sipping, not gulping, and some infants may struggle to draw liquid without slight tilting.

Compared to more complex models like the Dr. Brown’s weighted straw cup, the NUK Small Learner keeps things refreshingly simple—perfect for parents prioritizing ease of use over advanced features. It’s not the flashiest, but it excels in core functionality, making it a top pick for budget-conscious families who want reliability without bells and whistles. While it lacks measuring marks and a weighted straw, it outperforms many pricier options in durability and ease of cleaning.

Step into the future of sippy cups with the Dr. Brown’s Milestones, a game-changer for independent drinking thanks to its weighted silicone straw that follows the liquid—no matter how your baby tilts or flops the cup. The 9-ounce capacity is generous for a 6-month-old, reducing refill needs during meals or outings, while the contoured body and side handles fit perfectly in emerging grips. This cup doesn’t just hold liquid—it supports true developmental milestones, helping babies master new motor and oral skills with confidence.

During testing, the weighted straw proved magic-level effective—even when the cup was tipped sideways or upside down (as all babies inevitably do), liquid flowed smoothly. The spill-proof sliding lid seals tightly, making it a travel-ready favorite for diaper bags and stroller cup holders. We appreciated the clear measuring marks, which help track intake—a subtle but critical feature for parents monitoring hydration or formula ratios. However, the straw requires a dedicated cleaning brush, and tiny hands can sometimes jam the lid mechanism.

When stacked against the Munchkin 360 or the NUK model, Dr. Brown’s wins on versatility and long-term use, though it’s slightly bulkier. It’s the best overall performer for parents who want one cup to grow with their baby, combining durability, smart design, and developmental support. While not the cheapest, it offers exceptional value through feature density and build quality, outclassing simpler models in both performance and peace of mind.

Meet the SAMiGO Silicone Sippy Cup—a leak-resistant fortress wrapped in soft, squeezable silicone that laughs in the face of toddler chaos. Its firm lid and double-seal design mean drops, tosses, and even determined chewing won’t trigger a flood—making it a must-have for mess-averse parents. The see-thru measurement window lets you check liquid levels at a glance, no opening required, while the 6-ounce capacity is ideal for snacks, sips, or short outings. It’s not just tough—it’s thoughtfully built for real-life parenting battles.

In rigorous drop tests and car seat trials, the SAMiGO didn’t just survive—it thrived. The thicker silicone body absorbs impact like a pro, and unlike flimsy plastic cups, it doesn’t crack or warp after repeated drops. We filled it with juice, water, and milk—no leaks, even when shaken vigorously. The straw design requires moderate suction, so it’s better suited for babies 9 months and up who’ve got some sipping experience. While it’s microwave and dishwasher safe, the lack of a cleaning brush may frustrate some users.

Against the Moonkie or Dr. Brown’s, SAMiGO stands out for pure leak resistance and durability, though it sacrifices some developmental versatility. It’s the best choice for parents who prioritize cleanliness and convenience over multi-stage conversion. While it doesn’t transform into an open cup, its rugged, all-in-one build offers unmatched reliability—making it a clear leader in spill-proof performance despite a slightly higher price tag.

The Munchkin Miracle 360 isn’t just a sippy cup—it’s a dentist-approved oral development tool disguised as a toddler tumbler. Its spoutless, 360-degree drinking rim mimics an open cup, encouraging proper lip, tongue, and jaw movement—critical for speech and dental health. The 7-ounce capacity gives plenty of room for hydration, and the dual-pack format means backups are always on hand for spills or wash cycles. This cup doesn’t just reduce mess—it actively supports healthy mouth development from day one.

In action, the rim-seal technology works flawlessly—babies can sip from any side, and the cup seals automatically when not in use. We tested it on wiggly 7-month-olds: no leaks, even when dropped face-down on hardwood. The handles are easy to grip and removable, allowing progression to independent cup use. However, the rim can be tricky for beginners who haven’t mastered suction, and some parents report difficulty cleaning the inner seal without disassembly.

Compared to the MAM or NUK models, the Munchkin 360 is more developmental, less transitional—perfect for parents focused on long-term oral health over bottle mimicry. It’s the best choice for parents who want to skip the sippy stage and move straight toward open-cup skills. While it’s pricier than basic models, its developmental edge and dual-pack value make it a standout investment—especially when weighed against the simpler, less functional designs of its peers.

The Moonkie 3-in-1 Training Cup is a developmental Swiss Army knife—a single cup that evolves from straw to spout to open cup, guiding babies through every drinking milestone. Its soft food-grade silicone is gentle on gums and teeth, while the double-seal lid ensures no leaks during play or travel. The 4-ounce size is perfect for first sips, and the valved straw prevents choking, making it a safe, progressive tool for babies as young as 4 months. This isn’t just a cup—it’s a growth companion.

During testing, the stage transitions were seamless—switching from straw to open cup took seconds and helped our 10-month-old adapt quickly to new drinking mechanics. The compact size fits tiny hands, and the non-choking valve delivered steady, controlled flow. We loved the cleanable simplicity—all parts disassemble easily, though the small size means more frequent refills. The silicone body resists stains and odors, but the lightweight build feels less durable than thicker models like SAMiGO.

Next to the Munchkin 360 or Dr. Brown’s, Moonkie wins on long-term adaptability, though it sacrifices capacity and leak-test toughness. It’s the best multi-stage option for parents who want one cup to last through weaning and beyond. While it can’t match the spill-proof fortitude of the SAMiGO, its developmental versatility and safety-first design offer unmatched value for families focused on milestone progression over pure durability.

The Munchkin Gentle Transition Cup is a gentle giant for sensitive gums, built around an ultra-flexible accordion-style silicone spout that bends and moves with baby’s mouth—no pressure, no pain. The 4-ounce size is ideal for early sipping sessions, and the see-through body with measurement marks lets parents monitor intake precisely. With removable anti-slip handles, it supports growing motor skills while staying comfortable for tiny hands. This cup is engineered for empathy, making it a top ally for fussy feeders or teething babies.

In real use, the spout’s flexibility proved a game-changer—babies who resisted stiffer spouts took to this one instantly. The spill-proof seal held up during drops and shakes, though aggressive chewing occasionally dislodged the spout if not fully snapped in. The compact size makes it travel-friendly, but it requires more refills than larger models. Cleaning is simple—no small valves or straws—just rinse or toss in the dishwasher.

Against the MAM or NUK, the Munchkin Gentle stands out for comfort over capacity, making it ideal for early transitioners with tender mouths. It’s not meant for heavy hydration sessions, but for short, soothing sips, it’s unmatched. While it lacks the advanced features of Dr. Brown’s or Moonkie, its focus on gum sensitivity and ease of use makes it a quiet champion among starter cups—especially when compared to stiffer, less forgiving designs.

The MAM Starter Cup shines with ergonomic brilliance—its ultra-light body and contoured shape fit naturally in a baby’s palm, encouraging proper grip and independent holding from day one. The extra-soft spout is gentle on gums, while the non-slip handles provide secure traction even with sticky fingers. It’s designed like a tool, not a toy—every curve and texture serves a developmental purpose. Add the included dust cap, and you’ve got a hygienic, portable solution perfect for daycare or travel.

In testing, the lightweight build was a double-edged sword—easy for babies to lift, but less stable when knocked over. The 5-ounce capacity balanced well between usability and manageability, and the spill-free valve worked reliably on carpet and tile. However, the cup offers no measurement markings, making it hard to track intake—a notable omission for new parents. The dust cap adds convenience, but it’s easy to lose if not clipped securely.

Compared to the NUK or Munchkin models, the MAM cup prioritizes ergonomic design over feature density, making it a top pick for parents focused on motor development. It doesn’t have a weighted straw or 360 rim, but its intuitive shape and soft spout create a seamless transition experience. While it lacks some tech-forward perks, its focus on form and function gives it a refined edge in usability and comfort—especially when contrasted with bulkier, less intuitive rivals.

The Tommee Tippee Starter Weighted Straw Cup is a hydration hero built for any-angle drinking, thanks to its soft silicone weighted straw that follows liquid wherever it goes—perfect for babies still mastering coordination. With a 10-ounce capacity and antibacterial straw technology, it’s designed for longevity and hygiene, while the leak-proof, anti-valve design laughs at drops, shakes, and upside-down adventures. This two-pack set means double the convenience, making it a smart choice for active families who hate running out of clean cups.

In real-world tests, the weighted straw delivered flawlessly—babies could drink while lying down, reclined, or wildly wiggling, with no need to tilt. The anti-valve system prevented leaks even when tossed in a diaper bag. We appreciated the easy-grip handles, which stayed comfortable during long sipping sessions. However, the larger size can be bulky for small hands, and the straw requires regular cleaning to maintain antibacterial performance.

Stacked against Dr. Brown’s, the Tommee Tippee offers similar tech with better value—two cups for less than some single models. It’s the best for any-angle drinking, especially for babies who hate being repositioned. While not as compact as starter cups, its capacity, hygiene features, and leak-proof confidence make it ideal for growing toddlers—outperforming smaller, less capable models in both function and long-term use.
