Feed Me I'm Yours began as a local fund-raising cookbook for the Minneapolis chapter of the Childbirth Education Association (CEA) in 1974.

Lansky, then a new mother and recent transplant to suburban Minneapolis from New York City, was not familiar with local group 'favorite-recipe' fund-raising cookbooks.

With only two groups working in meetings and only one name suggested for the cookbook, the project was presented to CEA, who quickly agreed to fund the book's first printing.

[1] Lansky's first book is still one of the highest-selling baby/toddler food cookbooks in the United States,[2] which has sold over 3 million copies.

In an interview, Lansky stated: "I read what was available on divorce but no one book had all I needed in one place so I wrote the one I wished I could have found for myself...

And in the midst of the Beanie Baby frenzy of that time, Lansky created KoKo Bear: the Divorce Doll for Kids.

Lansky was interviewed by Meredith Vieira on The View, where she introduced the KoKo Bear doll to a national audience.
