Fallon's 'Your Baby's First Word Will Be Dada' will be published by MaCmillan imprint Feiwel and Friends next June 9, reported Huffington Post.
Fallon wrote a children's book, 'Snowball Fight!' back in 2005, but this is the first one he's written since becoming a father.
Te TV host's book is said to be a hilarious account of every father's secret campaign to ensure that their babies' first word is Dada -- not Mama!" Throughout the story, illustrated creatures -- from cows, sheep, and horses to mice and frogs -- try to coax their babies into saying 'Dada'.
Fallon, 40, and film producer wife Nancy Juvonen welcomed Winnie Rose last year via gestational surrogacy.
