✅ INCLUDES: Three Blue 9oz. PopYum baby bottles (260 ml) with #2 medium flow anti-colic nipples and a funnel which makes loading formula a breeze and stops formula from falling into the water chamber and contaminating the water. ✅ ONE HAND ONLY: PopYum stores formula and water separately in the bottle. When hunger calls, simply press the buttons (or 'Pop'), shake a few times, and 'Yum'! PopYum is the only bottle which was designed to be used with one hand only so you can comfort baby or multitask with your other hand. ✅ GREAT WITH BREAST MILK: Breast milk (and/or water) is completely isolated in the bottom of the bottle. It never touches the leak points of the tip of the nipple and anti-colic vent until you press the PopYum buttons which releases the agitator and allows the breast milk into the nipple area. ✅ ONLY 5 PARTS: PopYum has the same number of parts as many regular baby bottles and has up to 60% fewer parts as compared to other formula making bottles! The wide design eliminates the need to for a bottle brush (you can just use a regular sponge) and it's top rack dishwasher safe. ✅ BPA FREE: PopYum is made of only medical grade silicone and premium polypropylene. PopYum is BPA, BPS, latex, lead, nitrosamines, PET, phthalates, PVC and TPE free.
