You don't want to distract the mother from what she is doing. Distraction will cause the labor to sometimes slow way down and or stall all together. Some people want to rush things or they imagine the mother needs to be rescued and thank goodness they are there to do it. This behaviour is a common form of birth anxiety displayed by people who are not really comfortable with birth and don't view it as the natural body function that it is. Birth is not something to fear or fix.
Nothing is broken.
Leave the process alone and keep your hands to yourself. While waiting for the next contraction, you could quietly wipe the baby's face off, especially if he is attempting to breath, which he might very well do. The baby will likely be born during the next contraction. Allow the mother to smell, inspect and get to know her baby right away - the very second she turns around. The baby will immediately begin to breath and look around as mother licks him dry and welcomes his arrival.
