Do other mums feel the same?

My Little boy is almost 6months old and i made the big mistake early on of reading the books such as Gina Ford,Baby whisperer etc,as much as they are a guide they have left me stressed about things for instance at bedtime they say baby needs to learn to self soothe...as easy as it sounds doing it is another matter and i then feel that if i put dummy in or he goes down asleep after his bottle etc that this is wrong and that he will never learn to do thi,or rocking him to sleep is a bad habit etc. I know that you have to do what is best for your baby and they are all different but its stressful knowing that they are right but what i may do isn't!! Do other mums out there feel like this?
