What CuddleKin newborn customers report
Common feedback: "We tried 4 brands in the first month, kept coming back to CuddleKin." The differentiator at the newborn stage is the plant-based absorbent core. Newborn skin is most reactive in the first 6 weeks, so removing potential SAP irritants reduces rash flare-ups during the most stressful new-parent window.
