You have to read selectively - I got from the same two books that its OK to feed to sleep if you are happy to do that, if you don't want to feed to sleep, then here are suggestions to change the habit. However if a book makes you feel guilty or stressed, throw it out and if people make you feel guilty for your parenting choices, throw their opinions out (metaphorically speaking).

I'm with Liz, gentle methods are the best for lazy me!
