In 2015, the Estonian junior women's team qualified for the 2015 World Junior Curling Championships where Laidsalu played second on the team skipped by Marie Turmann. At the tournament, the team finished in eighth with a 2–7 record. Because of their bottom three finish, they were relegated to the 2016 World Junior B Curling Championships in order to earn their spot at the 2016 World Junior Curling Championships. At the B tournament, they just missed out on qualifying for the Worlds, losing the bronze medal qualifying game to Hungary.
