WebA logistic regression model makes predictions on a log odds scale, and you can convert this to a probability scale with a bit of work. Suppose you wanted to get a predicted probability for breast feeding for a 20 year old mom. The log odds would be-3.654+20*0.157 = -0.514. You need to convert from log odds to odds. http://www.columbia.edu/~so33/SusDev/Lecture_9.pdf
