Infants and toddlers are uniquely vulnerable to chemical exposure. Their bodies are still developing, their detoxification systems are immature, and they spend more time on floors and put objects in their mouths.
Why We Rated It This Way
Dr. Brown's glass option is an excellent choice. The BPA-free plastic option is better than older BPA-containing bottles but still plastic. If choosing Dr. Brown's, always choose the glass option.
