We picked up these bottles when our newborn grew out of the tiny little bottles they provided at the hospital. The initial draw was the darling patterns and bright colors. As we used them more and more, however, we discovered how awesome these bottles are! They were a perfect fit in a small refrigerator and in our diaper bag. Not tall and thin like most bottles, but short and stocky. They had a firm rubbery nipple top that is easily removable and very easy to clean unlike some of the other bottles we tried that had ultra-soft, flexible material with lots of creases that were a pain to clean. The important fact that they lack BPA is of HUGE importance to us as our other go to bottles are Dr. Brown's Glass Natural Flow. We love them, our baby loves them. SO happy with this product.
