Overview
NUK's Smooth Flow Anti Colic bottle comes in a 5-ounce size with an elephant print, sold as a 3-pack. Each bottle weighs about 0.35 pounds and is built for infant feeding.
NUK markets the Smooth Flow line around its anti-colic venting, designed to cut down on the air a baby swallows while feeding. At 5 ounces, this size suits newborns and younger infants more than babies who've already moved to larger feedings.

- 3-pack
- Anti-colic Smooth Flow venting
- Infant age range
Who it's for
Parents of newborns or younger infants wanting a smaller bottle size with anti-colic venting, especially useful if gas or fussiness during feeding has been an issue. Families whose babies have moved past 5-ounce feedings will find this size too small.
Strengths and trade-offs
Drawn from this product's published specifications.
- Anti-colic venting built into the design
- Sold as a 3-pack
- Sized for newborn and younger infant feedings
- 5-ounce size will be outgrown as feeding volumes increase
Performance notes
The anti-colic vent is the core mechanism, built into the Smooth Flow design to reduce the air a baby takes in while feeding, which is a common cause of gas and spit-up. At 5 ounces, the bottle matches newborn feeding volumes rather than the larger amounts older infants need.
