By 3 years of age, I had tried EVERY straw or sippy cup on the market for my toddler. Most were difficult to clean. All lost parts. None fit in my cabinet well. Finally, FINALLY I found the CamelBak Eddy Kids Water Bottle! It comes apart into multiple pieces to clean! You can buy replacement valves and straw pieces if they get lost or damaged! And they are short, squat, and fit perfectly in the InterDesign Lazy Susan Kitchen Cabinet Organizer I have put all of my sippy cups and baby bottles in! Throw away all those other hard to clean, difficult to repair cups. It’s the CamelBak for the win, and my ONLY straw cup of choice!
