Hi Dominique, thank you for taking the time to write this, and I'm sorry the cup hasn't worked out for your little one so far. That is not the experience we want any family to have. There are a few small things that can affect how easily these flow, and we would genuinely love to help get them working for you, or make it right. Please reach out to us at info@roobearkids.com and we will take care of you personally.
Warmly, the Roobear team
