False-since up to 30% of the babys blood can be in the cord and placenta at the time of birth, clamping and cutting the cord immediately can mean that the baby does not get his or her full supply of blood back. a recent study found that delaying cord clamping by 2 minutes allows the babys blood to return to him or her. delaying cord clamping can also benefit babies who are slow to take their first breath; they are still receiving oxygen from the cord. only in some cases, such as when the cord is wrapped tightly around the babys neck, does the cord need to be cut sooner rather than later.
