Don't ever listen to anyone who tries to tell you that what you are doing is 'wrong' and that baby should do this, shouldn't do that etc. I think books can be great as a reference, particularly as bub gets older (and turns into a toddler, which is a whole new kettle of fish) but I firmly believe that parenting style is unique to everyone.
Also don't listen to anyone who says that if you pick your baby up when they cry and if you rock or feed your baby to sleep that they will grow up too attached and will never learn to settle themselves - so not true.
