We've used Nuby sippies for milk since we got rid of bottles after LO's first birthday. She drinks juice/water from other sippy-style cups or straw cups but this style (short, with handles) is the only thing that she'll drink a full cup of milk out of. Over the last month or two she's destroyed the nuby spouts by chewing them, expanding the slits that the milk comes through and they leak EVERYWHERE. I've bought replacement spouts and used almost all of them (at $2 each they're almost as pricey as the cups!) I decided to try some hard spout ones (penguin Avent ones) but they leak where the cup and cap screw to one another- when she holds it sideways or upside down or lays it down, tons of milk leaks out down the sides when it's set right side up. I really need to find another one that is this shape, but has a hard spout and WILL NOT LEAK! UGH!!!!! Anyone have any tried-and-true suggestions?
