Inclusion Criteria: * mothers delivering at 35 weeks or greater * mothers who have had at least 1 previous child that received phototherapy for hyperbilirubinemia * multiple gestations can be included unless the neonate does not meet criteria for delayed cord clamping as described below or due to concerns about safety of delayed cord clamping for timing of delivery of the 2nd twin (ie: 2nd twin requires immediate delivery intervention) Exclusion Criteria: \- Neonates who do not meet criteria for delayed cord clamping (any infant that any provider in the room felt needed evaluation by the neonatal transport team immediately so that the infant would be handed off for resuscitation. If the patient required delivery by cesarean section the delayed cord clamping protocol would be abandoned).
