My son may be only five months old, but denied like many breast children the bottle. A Sippy Cup he did not like, too, but he is really into tea from a normal cup, but still was quite a mess, because he always tore the cup. The training cup was there for us a great solution! Of course, he did not drink so myself, but it's easier and to give much less mess him something to drink. Even if the cup falls times he remains tight. Really a good cup, strong buy recommendation from me!
