The LEGO Duplo Primo theme, introduced in the mid-1990s, was designed for the youngest builders, typically aged 6-24 months. Key sets include "Primo Tumbler" (2091), which featured large, rounded pieces that could tumble and roll, promoting motor skills and coordination; "Primo Cannister" (2092), a storage set filled with various Primo blocks and elements for basic stacking and building; and "Medium Stack 'n' Learn Set" (2082), which included a variety of colorful, easy-to-handle pieces to encourage early learning and exploration through stacking and sorting activities. These sets were specifically created to be safe and engaging for infants and toddlers.

For younger builders, LEGO Primo debuted as a pre-DUPLO system introducing infants to basic stacking play. Aquazone launched as LEGO’s first dedicated underwater adventure line, featuring the Aquanauts and Aquasharks. Castle expanded with the Royal Knights faction, while the company mourned the passing of Godtfred Kirk Christiansen, whose System in Play philosophy shaped LEGO’s legacy.
