We bought the mug for our son can make first attempts with the drinking cups. However, he is not thought of this, because the child must have been good, the liquid that comes out and can swallow a little dose, how high it the cup, otherwise it drops to the child on the chin down, because just coming too much. Soaked the flows namely easy, when you press the plate with the lip when tilted. How much flow can be regulated only by the slope and could not yet assess our son. The idea is great and for later maybe also good for your first attempt but not really well suited. In addition, after drinking always a small rest remains up in the drinking groove, which then drips out when you turn or overturn it. I find, however, not so bad, because it is just a bit. So basically a good idea, but not for beginners right drinking. Since the cup of Lovi is considerably cheaper, because there you have to really suck, so that something comes and then also comes just as much as you just sucks. We reserve the cup for later yet.
