Had this cup already for my big and he has used it until he was 2 years old. He was a child and still has taken no bottle after weaning. However, nothing practical on the go until he could drink from the aluminum bottle. No. 2 is doing the first drinking learning experiments and by the oblique opening I can see how far I have to tilt the cup. For me would be last of all only important that it may still could be in another material the cup, because I do not like plastic, but then he would not be back so appropriate that the little later even takes the cup and drinks.
