Choosing to pump gives you back some well-deserved freedom and flexibility, but the whole process can get messy and complicated. Our Pump and Go range makes everything simpler. By using a single pouch to pump, store, warm and feed, there's no need to transfer milk at any stage, so you'll never lose a precious drop. This unique, Breast Milk Pouch Bottle from the Tommee Tippee Pump and Go range is the perfect fit for Pump and Go pouches. Simply click pouch into the bottle so your baby can enjoy every drop. The Pump and Go breast milk pouch bottles come with a Closer to Nature Slow Flow Nipple for a smooth transition from breast to bottle. Note: Anti-colic nipples cannot be used with the pouch bottle. The Closer to Nature Slow Flow Nipple with a super-sensitive valve eliminates excessive air flow, so little ones ingest more milk and less air. The Pump and Go breast milk pouch bottle is easy to clean and can be used in the dishwasher (top shelf only). Pouches are not re-usable.
