Overview
Boon Nursh Bottles - Slow Flow are silicone baby bottles sized at 4 ounces, built for newborns just starting on a bottle. The soft silicone body collapses as your baby feeds, which is the defining trait of the Nursh line. Slow flow nipples keep the pace closer to breastfeeding speed.
Nursh bottles skip the rigid vent systems most bottles use and instead let the silicone sleeve compress on its own, an approach Boon markets toward reducing air swallowed during feeds. That makes them a common pick for breastfed babies moving to a bottle, or for parents alternating between breast and bottle. At 4 ounces they suit early newborn portions rather than the larger feeds older babies take.

Who it's for
Best suited to parents of newborns who want a soft, breast-like nipple feel and are starting small with 4 ounce portions. Families supplementing breastfeeding often reach for this line specifically for the slow flow pace.
Pros and cons
- Slow flow nipple matches early newborn feeding pace
- Soft silicone body designed to collapse during feeds
- Compact 4 ounce size fits newborn portions
- 4 ounces is too small once your baby needs bigger feeds
- Silicone bottles need replacing sooner than hard plastic
Performance notes
The silicone body of a Nursh bottle collapses as your baby draws milk out, which is meant to limit the air the bottle pulls in compared to a rigid plastic bottle with a separate vent. Slow flow nipples release milk at the lowest rate in the line, matched to newborns still building feeding stamina.
