I agree with everything LE and others have said - it is a scary experience if you are watching but when you do your training you will be taught what to do to 'encourage' the little blighters to start breathing and all that adrenaline and desire to help will be channelled correctly.
After many years and many little blighters that decide to scare us s**tless it is still a heart thumping few minutes untill that big yell
. But it feels so much better when you can confidently deal effectively with it. (There are still the occasional sad outcomes and we still shed a few tears then)
Also remember that a newborn's capacity to withstand apnoea(no breathing) before damage is greater than an adult's so you have time to 'teach' the baby the error of it's ways before damage occurs
