The author of a controversial new book is calling on women to prioritize mothering for the first three years after giving birth.

Erica Komisar, author of "Being There: Why Prioritizing Motherhood in the First Three Years Matters," believes that we are seeing a cultural devaluation of mothering, and we are not prioritizing our children.

On "Fox & Friends" this morning, Komisar said she has noticed an "epidemic level" of children with emotional problems related to the absence of mothers.

"What I say in my book is: more is more," Komisar said. "The more you can be there emotionally and physically for your children, the better off your children will be."

She explained that the first three years of a child's life are particularly critical for brain development, so whether a mother is working or non-working, it's about focusing on the child and really "being there."

"It really isn't a book about working versus not working," Komisar said. "It's about prioritizing ... prioritizing your children in the first three years."

"We think that life is long and you have many, many years to work and be ambitious and make money. You only have a few years to have that great influence on your children."
