Oxytocin is the hormone mainly responsible for contractions during labor and bonding. Oxytocin is even found in breast milk. Studies show that a nursing mother is often calm and relaxed. Pitocin, on the other hand, is a synthetic form of oxytocin that doesn’t offer all of the benefits of its natural counterpart. It’s important to understand the distinction between oxytocin and pitocin, and to discuss it with your doctor, during your pregnancy, before labor even begins.
