Does anyone else have this problem with Chobani?

I buy a tub of it and it goes bad pretty quick.

I would think it would last at least a week but I've been so unhappy that I've started putting the date that I open it to see how long before it goes bad.

I'm talking within 4 days, it is not edible. I taste it at least once a day before feeding the kids.

I always use a clean spoon. I don't lick the spoon between scoops to prevent bacteria growth. I always put the lid back on before returning it to the fridge.

I feed the kids yogurt once a day but will start feeding them yogurt twice a day.

It's crazy that a whole tub like that doesn't last til until you get to the bottom.
