Research & Science: Why We Choose Glass Over Plastic

Why Microplastics Are a Concern

What are microplastics?
Tiny plastic particles that can shed from bottles when exposed to heat, friction or sterilisation.

Why it matters for babies:
Infants’ gut barrier and immune system are not fully mature, which can increase susceptibility. Studies show that microplastics and associated chemicals can alter gut permeability, provoke inflammation, or disrupt the microbiome. (https://pmc.ncbi.nlm.nih.gov/articles/PMC9611505/)

What the Science Says

We believe parents deserve the facts. Here are key studies that shaped our choice:

Microplastics in Baby Bottles
A 2020 study published in Nature Food found that plastic baby bottles can release up to 16 million microplastic particles per liter during sterilisation and formula preparation. (https://www.nature.com/articles/s43016-020-00171-y)

Health Risks of Microplastic Exposure
Research suggests microplastics have been shown to accumulate in the gastrointestinal tract, disrupting the gut microbiome, and causing dysbiosis-a harmful imbalance between beneficial and harmful bacteria. This disruption has been linked to various health issues, including gastrointestinal disorders, systemic inflammation, and chronic diseases and babies are especially at risk due to rapid growth and immature digestive systems.  (https://www.frontiersin.org/journals/cellular-and-infection-microbiology/articles/10.3389/fcimb.2024.1492759/full)

Safer Alternatives
Studies consistently recommend glass and silicone as safer materials because they are stable under heat, free of BPA/BPS, and do not shed microplastics. (https://www.consumerreports.org/babies-kids/baby-bottles/popular-baby-bottles-with-no-detected-bpa-lead-or-phthalates-a1174352020/)

Our Safer Choice: Glass + Silicone

  • Borosilicate Glass: Highly durable, resistant to heat and sudden temperature changes and chemically stable.
  • Food-Grade Silicone Sleeve: Adds grip, protection and thermal insulation while remaining toxin-free.
  • Plastic-Free Feeding: Zero microplastics leaching, zero BPA, zero BPS.

For Parents Who Want Proof

We know parenting comes with enough second-guessing. That is why we show you the science, so you can feel confident with every feed.
