Growing up in the center of the collaboration of efforts between her aunt and father, Jansson gained an intimate window into the creative processes behind the Moomin comic strip series.

[12] In May 2003, the Finnish Embassy in London arranged for events to surround the recent translation of Tove Jansson's 1972 Sommarboken, a novel which featured the fictionalized life of the young Sophia on an island.

[15][16] She would write in more detail about this topic in 2006 in the Scandinavian Review,[17] and again in 2010 for The Guardian, when she explained the nature of her relationship with the rest of the family including her grandmother Signe and Tove's partner, Tuulikki Pietilä.

[20][21] She has also featured in Paul Gravett's 2006 documentary film, Moomin's Memoirs, presented at the March 2007 Tove Jansson Conference in Oxford.

[24] In June 2004, Jansson was invited by the Consulate General of Finland to the 31st "Dreams & Visions" Annual Children's Literature Conference in California.
