PopYum is a better everyday baby bottle that makes feeding more natural and supports an active parenting lifestyle. No more having to hand mix formula in awkward spots, keep pre-mixed formula chilled or worry about leaky bottles. PopYum stores water and formula separately in the bottle until hunger calls. With a single hand, simply pop (press buttons to release formula into water), shake a few times and yum! Prepare enough bottles for the entire day, around town, at daycare, and for travel. PopYums wide nipple and natural latch support a smooth transition from breast to bottle. The anti-colic vent returns air to the bottle, not babys tummy. The included funnel makes loading formula a breeze. Its also great at storing breast milk with absolutely no leaks. Breast milk or water is isolated from the nipple and vent which are the most common leak points. The wide bottle design is easier for baby to hold. PopYum reduces baby bag clutter by eliminating the need to carry extra water bottles, formula containers, and cooling packs. Made of only a few parts, PopYum saves daily cleaning time (no bottle brush required!).Created by concerned parents, PopYum is made of only medical grade silicone and premium polypropylene. We invite parents to compare our materials to those of any other bottle. PopYum is BPA, BPS, latex, lead, nitrosamines, PET, phthalates, PVC and TPE free.
