I missed the reading at Barnes and Noble. Dang. But there’s a story in the Daily News about Park Slope’s Louise Sloan, whose book, “Knock Yourself Up: No Man? No Problem!” is in bookstores now.

When Brooklynite Louise Sloan finally conceived her longed-for baby, there were no scented candles flickering in the background or sappy love songs playing on the iPod.
Instead, she lay on an examination table, her legs in stirrups.

Two years on, Sloan joyfully totes 16-month-old Scott, conceived in the doctor’s office with a stranger’s sperm, and the wide-eyed inspiration for her new book “Knock Yourself Up: No Man? No Problem!”

“I always wanted to have kids,” says Sloan, who originally hoped to raise a family with a female partner. “It didn’t happen quite the way I planned because I didn’t find the right person, but I am just so happy that I now have this beautiful little boy.”

The 44-year-old writer and editor is among an increasing number of women in New York City – mostly straight and some gay – known as “single mothers by choice.”
