GROSMIMI Baby Straw Cup 10oz (Sky Blue) — PPSU Spill‑Proof Sippy with Silicone Cross‑Cut Straw & Rotating Handles

The GROSMIMI Baby Straw Cup is a 10oz (300ml), spill-resistant PPSU sippy with a soft silicone cross-cut straw and 360° rotating handles made for babies 6+ months learning to drink.

This lightweight straw cup helps infants transition from bottle or breast to independent sipping with features built for safety, cleaning ease, and everyday durability. Constructed from premium PPSU and food-grade silicone, the cup focuses on a clean drinking path, reliable leak protection, and two straw firmness options so parents can match the cup to their child’s stage. The flip-top lid, easy-disassemble design, and compatibility with common sterilizing methods make it a practical daily cup for busy families.

How does the spill-proof system protect against leaks?

The cup uses a cross-cut, +Cut silicone straw combined with a flip-top lid to prevent spills when tipped or dropped. The straw only opens when the baby sips, and the lid seals securely when closed to keep liquids contained during transport.

• Cross-cut straw reduces accidental flow and blocks drips when idle
• Flip-top lid snaps shut over the mouthpiece for travel
• Sealed drinking path minimizes leaks if the cup falls or is tilted

What materials are safe for my baby’s drink and mouth?

All parts that contact liquid are made from high-grade PPSU or food-safe silicone — no metal or microplastic components in the drinking path. These materials are selected for heat resistance and durability, while remaining free from BPA and other concerning additives.

• PPSU body resists yellowing and repeated sterilization
• Food-grade silicone straw and mouthpiece gentle on gums
• No metal parts or microplastic layers in the sip pathway

How easy is the cup to clean and sterilize?

The GROSMIMI cup fully disassembles so every piece can be cleaned by hand or placed on the top rack of a dishwasher. It survives microwave warming and is suitable for steam or boiling sterilization, making it ready for regular use and frequent cleaning cycles.

• All parts detach for thorough hand washing
• Top-rack dishwasher safe for convenience
• Microwave, boiling, and steam sterilizer compatible

When should I switch from Stage 1 to Stage 2 straw?

Stage 1 is designed for babies 6 months and older and emphasizes a softer straw to protect new gums and first sips. Move to Stage 2 around 12 months or when you notice more biting and chewing — Stage 2 keeps the same leak control and flow but is firmer to resist damage.

• Stage 1: softer silicone for sensitive gums
• Stage 2: firmer straw for bite resistance and longevity
• Both stages maintain identical flow and seal performance

Who is this for? The GROSMIMI Baby Straw Cup is aimed at parents and caregivers introducing independent sipping to infants from about six months who need a dependable, easy-to-clean cup. It suits families seeking BPA-free materials, a compact 10oz capacity for on-the-go use, and a design that adapts as babies move from first sips to more confident drinking. The rotating handles and low-weight construction also make it appropriate for toddlers practicing self-feeding and grip control.
