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).

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.
