nuk smooth flow

NUK Smooth Flow bottles pair a Smooth Flow silicone nipple with a built-in nipple vent. According to the listings, the vent and nipple let the baby control suction and adjust the milk flow, which the product describes as an anti-colic design.

The Smooth Flow nipple adapts to a baby’s sucking: stronger suction increases flow and gentler suction slows it, so the flow matches the baby’s feeding pattern as described in the listings.

Listings show Level 1 (Slow Flow) and Level 2 (Medium Flow); the newborn gift set also includes fast‑flow nipples.

Available listings offer NUK Smooth Flow bottles in 5‑ounce and 10‑ounce capacities.

The listings specify bottles made of polypropylene/plastic with silicone nipples, and they are labeled BPA‑free.

Care notes in the listings recommend washing before first use and washing with soap and water; many items are listed as top‑rack dishwasher‑safe.

The newborn gift set includes two 5‑oz and two 10‑oz bottles with slow and medium nipples, three orthodontic silicone pacifiers, a Learner Cup transition kit, and two fast‑flow nipples.

Listings describe a wide‑neck bottle shape for easier cleaning plus a nipple vent designed to support anti‑colic feeding.

The listings state the suggested age as “Newborn and up.”

The two‑piece Learner Cup kit adds a soft spout and handles so a 5‑oz bottle can be transformed into a sippy cup, according to the listings.
