Doidy Cup I bought this to practice drinking from a cup, but it didn't work out, so I'm selling it. I washed it with water and tried letting my child hold it, but it didn't work... Perhaps it requires a knack, or maybe someone who can practice diligently. It's in excellent condition, having been purchased new and only used once. If you're considering Munchkin or Miracle Cup, please consider this as well. Thank you. Straw Mug Cup Baby Cup Baby Baby Food Drinking from a cup
