We talked to nurses and clinicians at NICUs and pediatric hospitals across the country who work daily with infants with feeding challenges. The biggest problem they faced? Lack of consistency in flow rates in the nipples produced and sold to consumers by top brands today. 

Many parents may be surprised to learn that there is no standard measurement for a slow flow nipple. One brand’s newborn nipple may be faster or slower than the next. In fact, clinicians told our team that they’ve even found varying slow rates in nipples manufactured by the same brand. This inconsistency can exacerbate or even lead to infant feeding problems.
