When I was pregnant with my first child i bought this book called what to expect when expecting. It helped me out a lot.
Was it easy to understand lol at least to some degree
I didn't read the exact same book but my sister did with her first baby and she loved it. She read it from FRONT TO BACK!! Lol. She also said it was an easy read and very interesting. Only reason I'm not reading it is because I have enough reading to do with nursing school. But Good luck.
