How do you prepare your self for delivery? I'm 23 years old first time to have a baby

There are hospitals and some private institutions that offer birthing classes and workshops. Some are for free and some have registration fees. You may check this out for the dates and venues: http://birthingisablessing.com/birthing-trainings-classes-workshops/

Asian Hospital and St. Luke's offer free birthing seminars. OBs and NICU nurses conduct the training. They cover everything, from 1st, 2nd and 3rd trimesters, labor, post natal and even the expenses. That's a good experience.
