When do you have the valve open and closed? Open only to remove for cleaning? Then locked for drinking?

It’s for the flow so they can suck on the water/liquid continuously

But do they have to suck to get the liquid out? My son doesn’t understand to suck

I wonder that too. The munchkin cup have to put your lip at the edge and suck but my daugther CANNOT drink... So i wonder if this is the same or not. Too bad that the maker of this video didn't answer back.... M
