Babies start cup training at 6 months post complementary feeding to build swallowing muscles and ease weaning.
Flaws of standard training cups:
Most parents confuse upside-down leakproofing with anti-spill performance. Splashes and choking are caused by unequal internal-external air pressure.
Ordinary cups vent only through the spout. Hot liquid or shaking creates high pressure that spurts out, triggering scalds, stains and airway choking. Hard suction also traps air to cause infant colic, while fast unregulated flow leads to easy gagging.
Patented constant-pressure anti-spill core system.
SUCVENT adapts its mature anti-choke bottle tech for this cup with a patented pressure-balanced structure to eliminate splashes fundamentally:
1.Integrated vent tab: Discharges hot air and excess pressure via a separate channel (bypassing the drinking spout). No spurting even with 70°C hot water or heavy shaking; minimal inversion leakage.
2.Built-in buffer pillar: Moderates liquid flow for a gentle, steady stream, safe for strong-sucking babies.
3.V-shaped bite valve: Dispenses liquid with light biting and seals on release. Gentle for weak infant suction, cuts swallowed air/gas, and suits teething habits.


3-stage age-adaptable feeding system
Swap spouts on one cup body to match oral development from 6 months onwards:
- 6–9 months (Bottle phase): Cross-cut breast-simulated nipple + gravity straw for smooth weaning
- 7–12 months (Transition phase): 32.8° soft duckbill spout, trains lapping motion and prevents dental misalignment
- 10+ months (Independent drinking): Straight straw spout with 360° gravity ball for drinking in any posture


Practical design perks
- 360° gravity straw: Food-grade silicone-coated stainless steel ball, ideal for night feeds & outings
- Fully detachable components: No hard-to-clean milk-residue crevices, simple sterilization
- Ergonomic dolphin handles: Easy for babies to grasp independently
- Durable marked PPSU cup body in soft neutral hues
