Critics of the book always cite the "cry-it-out" method and the feeding schedule. But I never had to let my children cry more than 10-15 minutes - and that was really rare - before they fell asleep. It may feel like an eternity when you are listening to baby cry, but in reality it's not long. As for the feeding schedule - I've had some of the most well-feed babies! My youngest is wearing 9 month clothes at 4 months! How can people say it will cause you to stave your children when it clearly says in the book to ALWAYS feed your child if they are hungry.
I truly believe if it was not for Babywise, we could not have considered having our children so close in age. It has been wonderful for us! The order and serenity to home life that a schedule that "works for you" brings is priceless. Everyone is more content and well-rested when they know what to expect.
