Went to buy diapers for the first time the other day (we just ran out from what was given at the baby shower) I want to use pampers in strictly all for pampers so I went and grabbed the biggest box of pampers I seen in size 3 got home and they didn't have the wet indicator line I got pampers baby dry diapers so is there I different type or once they start going up sized do they just not have the line?
