Lego Juniors

Lego Juniors (also known as Lego Jr. and stylized as LEGO Juniors) was a product range of the construction toy Lego, designed for children aged 4 to 7 years old. It acted as a transition from the Duplo to the regular Lego System. Lego Juniors initial release was on February 14, 2014, with the tagline Easy to build. It was the successor to the Bricks & More line released in 2009. Unlike its predecessor, Lego Juniors offered specialized bricks to make builds look more realistic while using fewer pieces for an easier build. The product line was discontinued by December 31, 2018 and rebranded as "4+" in 2019.

Overview
Each of the sets featured a small number of larger pieces, in order to be easy to build. The toy sets were marketed at children aged 4–7.

Development
Lego Juniors theme aimed to provide children to gain confidence, whether they are transitioning from Duplo or just starting to build with classic Lego bricks. Michelle Wilson, senior brand manager, LEGO Systems, Inc. said, "We know that construction play benefits young children on multiple dimensions nurturing cognitive and motor skills along with developing social, emotional and imaginative skills; we're thrilled to offer a new line to make it even easier for children to have a great first experience building."
