 Bianca is currently lying down and a doctor is examining her. With the help of the doctor, Bianca and Daniel were able to see their baby from the ultrasound monitor.

 "Congratulations madam, your child is a man. He is growing healthy, and all his organs are formed."

 A few minutes later Bianca was sitting in front of Doctor Kim. Ready to hear the advice of the female doctor.

 "Madam, you seem to have a lot on your mind. It's not good for your baby. You need to be calm, over-the-top emotions can stunt the baby's growth. I'll give you a prescription for vitamins. Doctor's advice at length.

 "Okay, doctor," Bianca answered obediently.
