First Time Mom

Hi everyone, Im only 22 years old right now. Im having a baby girl, my due date is on July 29 according to my Last Menstruation Period. Just wanna ask, can you give me any advices or any guidelines should I follow? Is there any thing I should consider being a firts time mom? Like can you tell me some of your experiences before that might help me to take care my new born in a right way. (for example, as they say, don't kiss often the newborn, something like that) Thank you ?
