Gilbert welcomed son Rhodes Emilio Gilbert Perry with Perry in February (15) and the 4 Non Blondes singer began writing new music following his birth.
Perry shared the tracks with Gilbert and her children and they are now working on an album together.
She tells Us Weekly magazine, "I started playing some stuff to her, and the kids were liking it. Then I thought, 'Wouldn't it be fun if you guys gave me topics and we'll call ourselves Dear Sounds, and it'll be an album for kids written by kids'.
"(But), I (also) wanted to do something the parents would like, since they're going to be the ones listening to it over and over."
Gilbert has a daughter and son from her previous relationship with television producer Allison Adler.
