5 Phases - Hybrid Baby Bottles

About 5 Phases

Best of both worlds

Like all moms, Christine Barlow wanted nothing but the best for her babies. When it came to bottle feeding, she worried about plastic, so she opted for non-toxic, easy-to-clean, and recyclable glass instead. However, there was one drawback—glass can break. That’s why Christine created a hybrid bottle so every baby can have the best of both worlds.

5 Phases offers all the health benefits of glass, plus the durability of plastic. The unique design features a glass bottle fully encased in a see-through, BPA free sleeve.

With 5 Phases, you and your little one can raise a glass bottle without worry.
