First, we tried to offer our child water from an ordinary bottle, then we tried a sipper bottle of NUK. From the drink our child though a bit but our feeling is not enough, so let's try this bottle. Positives: It runs out of nothing, yet is sufficiently liquid out while drinking. It is small and light and can itself be taken in hand, so the child automatically is drinking more. The spout is big enough and is much better accepted. You can clean the bottle in the dishwasher.
