When does the whining stop.

My son literally whines over EVERYTHING he’s 19 months and it doesn’t matter what he’s doing he just does it. I try asking him what he wants or what’s wrong and obviously try to see for myself what the issue is but it’s literally nothing! He just does it. Is there a way to stop this?! It drives me insane. I know he’s a child but for some reason the sound like pierces through my ears. I can deal with his crying and fits but lord the whining drives me mad.
