In the early 1990s, Daum joined with Linda Carson, Alison Kelly, Robin Nichol, Barbara Pollard and Deborah Williams to write and stage the collective play Mom's the Word, a "kitchen table cabaret" about motherhood.
Daum, Kelly, Nichol, Pollard and Williams reunited in 2005 to create the sequel show Mom's the Word 2: Unhinged, using a similar format to address motherhood as children grow into their teens.
