How to Choose, Clean and Care for Your Baby’s Bottles

Choosing, cleaning, and caring for your baby’s bottles may seem like a small part of the day — yet it quietly shapes your baby’s comfort, nutrition, and wellbeing. Whether you bottle-feed exclusively or occasionally, the way you handle every step makes a lasting difference.

At Cybele Star, we believe that real safety begins with smart design and informed habits. Here’s what truly matters when it comes to baby-bottle safety — and how to make it effortless.

1. Choosing the Right Bottle

Not all bottles are created equal. The safest ones share a few essentials:
They’re made from BPA-free, food-grade materials such as borosilicate glass, medical-grade silicone, or high-quality polypropylene. They have smooth surfaces that don’t trap residue and a simple structure that’s easy to clean.

When selecting bottles, look for recycling codes 2 or 5, which identify safe, BPA-free plastics. You’ll find this small triangle symbol embossed on the bottom of most bottles — a discreet but important sign of safety. Avoid bottles marked with code 7, as they may contain BPA.

If you combine breastfeeding and bottle feeding, choose a breast-like teat that eases the transition and a design with anti-colic vents to reduce air intake.

👉 Replace bottles regularly — especially when they become scratched, cloudy, or lose transparency. Over time, wear can trap bacteria and cause the gradual release of microplastics into the milk. A clear, smooth surface is always a safer choice.

Sometimes, the best bottle is simply the one that makes your day flow more smoothly — safe, practical, and perfectly suited to your baby’s rhythm.

2. Preparing Feeds — It’s More Than Just Warming

Preparation is the quiet foundation of safe feeding.

Clean hands. A clean surface. Sterilised bottles ready for use.

Always follow the instructions provided by the formula manufacturer — from the correct water temperature to the right proportions. These steps are carefully designed to ensure your baby receives the proper nutrients and to prevent bacterial growth.

When warming milk or formula, gentle precision matters — overheating can destroy nutrients and cause burns. The ideal temperature is around 37 °C, close to body warmth.

🍼 Stellar™ Portable Baby Bottle Warmer makes this moment effortless — its slow, even heat warms milk gradually and precisely, preventing hot spots and reaching the perfect temperature in no time.

3. Cleaning and Sterilising — The Foundation of Safety

True sterilisation starts with proper cleaning. Wash bottles, teats, and rings thoroughly in warm, soapy water to remove every trace of milk before sterilising.

Use dedicated bottle and teat brushes to reach threads, joints, and narrow areas where residue may hide. Rinse thoroughly to remove any soap before sterilising.

From there, choose a method that suits your routine — steam, boiling water, or UV-C sterilisation — each effective when done correctly. Never rinse again after sterilising, as it can reintroduce germs.

For parents who value simplicity, Lumen™ Portable UV Sterilizer offers a quick, water-free solution. Using UV-C LED technology, it removes 99.9 % of germs in as little as one minute — safely, silently, and without mess. Its tilt-sensor system adds an extra layer of protection by pausing the cycle if movement is detected, keeping eyes and skin safe.

4. Storing Bottles Safely — At Home and On the Go

Sterilising is only half the story. How you store bottles matters just as much.

Let every part air-dry completely — moisture encourages bacteria. Once dry, close each bottle with its lid to protect the teat from dust or contamination. Then store bottles in a clean, covered container or closed drawer, separate from used items.

Wipe drying racks and storage bins weekly to prevent mould or residue.

When you’re on the move, Lumen™ becomes your portable safeguard. Compact and fast, it allows you to re-sterilise bottles, teats, or accessories anywhere — from cafés to airport lounges — keeping every feed truly ready, wherever you go.

5. Designed for Confidence

At Cybele Star, safety is not a feature — it’s a language.
It’s the quiet precision of Stellar™, crafted from EU food-contact-certified materials, with medical-grade stainless steel, food-grade silicone, and smart sensors that think ahead — protecting, sensing, adapting.

And it’s the luminous assurance of Lumen™ — CE-certified, BPA-, phthalate-, and latex-free, and powered by pure UV-C LED light. No water. No heat. No waiting. Just clarity, cleanliness, and confidence in the palm of your hand.

Both are award-winning innovations, designed for those who seek calm over complexity, and certainty over chance.

Because true innovation doesn’t shout — it simply lets you exhale. 💛
