The Baby theme is designed for very young children and was first released in 2000 as part of the DUPLO style theme. It the predecessor of DUPLO Primo theme (1995-1996) then the LEGO Primo theme (1997-1999). LEGO Baby was discontinued in 2006. The bay parts where not that compatible with standard LEGO bricks since the bricks are larger to prevent babies from swallowing them. However, standard bricks of the same length and width can be attached to the bottom of Baby bricks and adapter pieces are also available.
2005 LEGO Sets
2005 shaped up to be a significant year for LEGO collections. Starting with the fact that LEGO System celebrated its 50th anniversary, we also saw a LEGO set designers change their techniques in set designing. 2006 marked the year that the skin color of the Star Wars minifigures changed from yellow to light nougat which also continued to various other future licensed themes. While this was a simple change, the value of sets saw high growth. 2006 introduced the LEGO City theme which replaced the Town theme, as well as Tiny Turbos under the Racers theme. However, in 2006 LEGO did discontinue Alpha Team and Baby.
