“We want to do better for our children. We want to teach them how to be kind to people. We want them to know how to care for themselves + their environment. It starts at home, and it starts early. With this in mind, Philips Avent natural glass bottle is our recommendation for the most eco-friendly bottle for feeding your baby. And it’s an easy way to reduce the use of plastics in your home. Made in the USA, the glass is BPA-free + thermal shock resistant, so it can be stored in the fridge and heated in the microwave. It’s easy to clean [with just four parts] and compatible with all Philips Avent natural nipples for a soft, moveable feel that supports an easy latch. The bottle’s unique airflow technology works to reduce colic + prevent upset stomach. A happy tummy means a happier baby. ”
