This is a trainer cup and my son took to it right away at 10 months. He has no problem drinking from it, which is great. It says it is no spill, which is mostly true. If you turn it upside down, it doesn't spill. However, he is always dropping the cup (or throwing it) and when it hits the ground, a ton of liquid gushes out, which is annoying. That said, we use it a ton!
