ELI5: Why can a baby scream endlessly for hours on end while an adult loses their voice after a short period?

I have a 2 month old colicky baby.  

Why is it that when I go to a concert and cheer/scream a bit for less than an hour I lose my voice, yet my child can scream until they make me deaf - FOR HOURS - and it's nothing to them?

It is because babys use the full potential of their lungs - kind of like opera singers. That way they don't Stress their vocal cords that much. We as adults don't do that anymore, our breathing is much more shallow, so we have to use our muscles as a compensation. And that is exhausting and you lose your voice.
