Review on Munchkin Simple Clean Straw Cup, 10 Ounce, 4 Pack, Blue/Green/Pink by Sandra Egan

Bought these to try out a different straw cup for my 18 month old who seems to get frustrated that the other spill-proof cups we have tried are hard to suck out of. One issue is that because these are not tight screw-on caps my toddler has figured out how to remove the lid and spill his water everywhere (we discovered this in the car of course). The split in the straw makes it easy to clean but sometimes it splits while in use in the cup. When that happens you can't get any water, causing a frustrated toddler. We've used them a few weeks but are already retiring them and moving onto something else.
