When my son's doctor told me to transition him from a sippy cup to a straw version, I knew my one-year-old was on the right path. Over the past month, my tot had taken a liking to drinking water out of a real cup with a straw. But that's only convenient when we're at home or in a restaurant. As a second child, my lil one is constantly on the go and we needed a cup that was easily transported. I reached out to a number of companies and put seven brands to the test. Check out the results!
