Do you know what's in your baby's bottle?
Every time a plastic bottle is heated, it releases millions of microplastic particles into your baby's milk. Most parents don't know this. We think they should.
The Hidden Problem
What research tells us about everyday baby products — and what most parents are never told.
Plastic baby bottles are the default in most homes. They're cheap, lightweight, and everywhere. But a growing body of peer-reviewed research is raising serious concerns about what happens at the microscopic level — especially when plastic meets heat.

This isn't about fear. It's about information. Every parent deserves to know the facts before choosing what touches their baby's food.
What the WHO Recommends
Before any product choice comes the most important choice: how you feed your baby. Here's what the world's leading health authority says.
WHO Primary Recommendation
Breast milk is the gold standard
The WHO recommends exclusive breastfeeding for the first six months. Breast milk is uniquely designed for human infants — it adapts to your baby's needs, provides antibodies against illness, and supports optimal brain development.
No product can replicate this. We say this not despite being a bottle company, but because we believe honesty builds real trust.
Exclusive Breastfeeding
The WHO recommends exclusive breastfeeding for the first 6 months of life. Breast milk provides ideal nutrition and antibodies that protect against common childhood illnesses.
Complementary Feeding
Nutritionally adequate complementary foods should be introduced at 6 months alongside continued breastfeeding to meet a growing infant's needs.
Continued Breastfeeding
Breastfeeding is recommended to continue up to 2 years of age or beyond, alongside appropriate complementary foods.
Proper Hygiene
Proper hygiene and safe food preparation reduce infant illness risk. This includes sterilizing all feeding vessels — the material of those vessels matters.
Adequate Nutrition
Adequate nutrition during the first 1,000 days (conception to age 2) is the most critical window for lifelong health and cognitive development.
Responsive Feeding
Infants should be fed based on hunger cues, not fixed schedules. Responsive feeding supports healthy growth and a positive feeding relationship.

The Material Science
When a bottle is needed — for expressed milk, water, or complementary feeds after 6 months — the material it's made from matters more than the brand on it.
Not all bottles are created equal. The difference isn't in shape or color — it's at the molecular level. Here's what happens inside the two most common materials when they meet hot liquids, sterilization, and daily use.
Plastic (PP/PE)
Most common baby bottle material
- Releases microplastics when heated or sterilized
- Can leach endocrine-disrupting chemicals
- Degrades with repeated washing and sterilization
- 'BPA-free' may still contain BPS or other bisphenols
- Environmental impact: 500+ years to decompose
Stainless Steel (304 grade)
Used in surgical and food-grade equipment
- Zero chemical leaching at any temperature
- No microplastic release — it's metal
- Withstands thousands of sterilization cycles
- Non-porous: no bacterial harboring
- 100% recyclable, infinitely reusable

The question isn't “which brand?” — it's “which material?” Once you know the science, the choice becomes obvious.
Our Approach
We didn't start with a product. We started with a question: why are most baby bottles still made of plastic?
We're parents. When we learned about microplastics in baby bottles, we looked for stainless steel alternatives. They were hard to find, expensive, or poorly designed. So we made one.
Baby365 exists because we believe the safest material should be the most accessible one. Not a luxury. Not a niche product. Just the obvious, sensible choice — for expressed breast milk, water, or complementary feeds after 6 months.
What we built
Baby365 Stainless Steel Bottle
304 food-grade stainless steel. The same material used in surgical instruments and commercial kitchens. No plastic components touch the liquid.
