Nervous

Has anyone else NOT had extensive experience with babies prior to being a mother? I'm 26 years old, and 28 weeks pregnant. I'm beyond educated on the topic but have never really had the actual practice of taking care of a baby. I'm so so so nervous that I'm not going to know what to do when my baby is born, that I'm going to just shake and be nervous because he is so fragile. Any advice? 😕
