A squeezable bottle? Comotomo Baby Bottles ($18) are also designed to mimic the breastfeeding process with their wide-neck design and smooth, skin-like feel, but the bottle's flexible design makes it unique in a sea of hard plastic/glass bottles. Made from 100 percent BPA-free, medical grade silicon, the bottle is actually squeezable, much like a natural breast, so baby can grab on and get comfortable.
