I agree with you. My 4 and 2 can and often do drink from a regular cup, but really, if I don't want to clean up or constantly refill when they drink outside, at night in bed, in the car, then a sippy cup is heaven sent. I think some kids develop an attachment to their sippy cup, it becomes a comfort object, or the way they can still be "babies" and that is where the problem is, not with the actual cup itself. AND many adults drink from coffee mugs with lids, and cups with straws and lids, and bottles with screw tops....so what's the difference?
