Are Microplastics Hiding in Your Baby’s Bottle?

Let’s talk about heated plastic bottles, greenwashing, and safer alternatives


Lawsuits are popping up against popular baby bottle brands like Philips Avent and Dr. Brown’s, claiming their bottles leach harmful microplastics when heated. While the bottles are typically safe at room temperature, heating them is where the risk kicks in.

Why it counts: Microplastics—tiny particles of plastic—could pose health risks, especially for infants who are still developing. The real concern? When these plastic bottles are heated, they can release microplastics into your baby’s milk or formula. Even though the health risks aren’t fully proven, many parents aren’t willing to take the chance.

Zooming out: This issue is part of a bigger consumer trend: greenwashing. Greenwashing happens when companies market their products as “safe” or “eco-friendly,” but behind the scenes, they may not be as clean as they seem. These lawsuits are calling out manufacturers for claiming their bottles are harmless while allegedly downplaying potential risks.

Behind the why:

  • As more parents and lawyers demand transparency, expect further legal action and scientific studies. In the meantime, switching to glass or silicone bottles can offer peace of mind, as these materials don't leach microplastics when heated.

  • Parents are becoming more aware of what their babies are exposed to, leading to a push for safer, more transparent product options. The lawsuits challenge companies to provide what they promise and not hide behind marketing.

Our take
If you’re worried, consider safer alternatives like glass or silicone bottles. They’re free of microplastics, even when heated, and are a smart swap for concerned parents.

Greenwashing is real, but so is the risk. Heating plastic bottles may release microplastics into your baby’s food, so it's worth looking into safer alternatives.

Sensory Bags, Bottles, and Jars

A safe way to let young children explore is by using sensory bags, bottles, and jars to appeal to younger children’s sense of sight and touch. Especially for babies, being able to squeeze a colorful liquid or gel-filled bag can be intriguing and engaging. For older preschoolers, a colorful, fizzing bottle or jar’s visual appeal can spark many curiosities and questions. All you need are unused bottles or jars with secure lids or freezer bags filled with leaves, gelatin, spare craft materials, washable paints, or birdseed.
