The only questions that matter are: is the baby safe, fed, rested and content? And are you coping?
If the answer to all of the above is yes, you don't need to change a thing, whether you are doing it 'by the book' or not. Ignore what other people are doing with their babies, ignore advice that you are making a rod for your own back, spoiling the baby etc - if it is working for you both it is working.
