First Lady gets kids' approval on book

First Lady Michelle Obama signs copies of her book, ‘American Grown: The Story of the White House Kitchen Garden and Gardens Across America, Tuesday in Washington.

WASHINGTON -- Michelle Obama gets a rare thumbs-up from her adolescent daughters for publishing her first gardening book.

The First Lady said her daughters Sasha, 11 and Malia, 13, were pulled in by the beautiful pictures and eventually read American Grown: The Story of the White House Kitchen Garden and Gardens Across America.

"They couldn't put it down and they started looking through and then they started actually reading it," she said. "Eventually, I got, actually, a thumbs-up."

Mrs. Obama spoke to a bookstore crowd at an anything-but-typical book signing, which required more than 200 attendees to stand in line for hours last week to get a wrist band, then go through security clearance and again line up for a few hours before Tuesday's signing at a downtown Barnes & Noble bookstore. She thanked the groups that were caught up in the rain while waiting.

The book, released two weeks ago, traces the story of the garden on the South Lawn and community gardens around the country.

The first lady was joined by children from Bancroft and Harriet Tubman elementary schools, both in Washington, for helping with the garden since its inception.

"They come to the White House, they don't get starstruck, they don't look around, they get to work," she said, as the crowd laughed. "They get our garden planted and harvested in a matter of 10, 15 minutes, sometimes 30 minutes. They just get it done."

Britta Nelson of Washington brought her three daughters-- around the ages of the first daughters-- to the book signing.

"I'm curious to see and read how she inspires parents, [and] find ways to have parents get their kids excited about healthy foods," she said.
