The epidural shouldn't effect the baby, and it shouldn't effect any part of mother besides the lower half being a bit numb. The problems start when the epidural is done incorrectly. If you feel a metal taste or hear a ringing in your ears, speak up. The doctors can't help you if you don't tell them what is going on. And don't be afraid to ask questions. The more you understand, the easier it is to know when to speak up.
