Youkebei Yeselino Flip‑Top Baby Bottle

Four Major Upgrades – A Bottle Designed for Natural Drinking Posture

The Yeselino Flip‑Top Baby Bottle reimagines how little ones drink. With an ergonomic 5° tilted body, a triangular grip‑friendly shape, and a lockable flip lid, this PPSU straw cup helps babies learn independent drinking without straining their neck or choking. Safe, comfortable, and thoughtfully engineered – your baby will love it after one use.

1. 5° Ergonomic Tilt – No Neck Bending, Upright Drinking

Most bottles force babies to tilt their head back, which can strain the cervical spine. Yeselino’s newly upgraded 5° tilted bottle body allows baby to drink while keeping the spine naturally straight.
✅ Protects bone health
✅ Prevents “head‑down drinker” posture
✅ Smooth liquid flow into the esophagus – no choking

2. Golden Triangle Bottle – Perfect for Little Hands

When you naturally hold a bottle, the web of your hand forms a triangle. Yeselino’s triangular bottle body fits this shape perfectly.

• Comfortable for moms to hold for long periods

• Easy for babies’ small hands to grasp

• Non‑slip, stable grip

3. Lockable Flip Lid – Stable & Nose‑Safe

• Slide up → unlock → press to open

• Slide down → lock → prevents accidental opening in bags

• The lid flips open 180° and stays stable – no wobbling, no slipping, never hits baby’s nose

• Lid is non‑detachable (integrated) – cleaner, more hygienic, no lost parts

4. Dual Anti‑Colic Vents – Easy to Suck, No Spraying

Two independent air return vents balance internal and external air pressure.

• Milk outlet + air inlet + air inlet

• Prevents air bubbles from mixing with milk

• Reduces swallowed air → less bloating, less crying

• No milk spraying when bottle is opened

Temperature‑Sensitive Scale – Thoughtful Protection for Every Feed

The left‑side scale changes color to warn you:

• Water temperature >45°C (113°F) → turns white → too hot

• Below 45°C → remains original color (safe feeding range)

No more wrist testing or unsafe mouth testing. Accurate, hygienic, and intuitive – even outdoors.

Skin‑Like Nipple – Realistic & Accepting

• Softness: Skin‑like feel, comfortable sucking

• Color: Imitates skin tone – gives baby a sense of security

• Shape: Similar size, matte texture, areola bumps – realistic simulation

Comes with size 10 nipple hole – suitable for babies over 6 months (some packaging says 7+ months).

Premium PPSU – Hard, Drop‑Resistant & BPA‑Free

Convenient Carrying Handle – Pull the Strap, Drink on the Go

The built‑in handle doubles as a carrying strap attachment point. Easy for little hands to hold and for parents to hang on a stroller or bag.

Laser Engraving Scale – Environmentally Friendly, No Ink

The volume markings are laser‑engraved – no ink, no fading, no chemical concerns. Clear and precise for measuring water or milk.
