I've just noticed you are in Melbourne...for what it's worth my DS loves water but his water consumption has cut right back now that the weather's gone cold. I think all you can do is persist by setting a good example by drinking water, leaving water bottles or cups lying around, offering water at meals or when you are out and about but you may find that she doesn't really take to water in larger quantities until summer time. My DS wasn't drinking a lot of water when he turned 1 in September last year but over the summer he really took to it.

Another thing to consider might be whether you put her sippy cups in the dishwasher? I noticed a while back when having a sip from DS' sippy cup that I could taste the detergent in the water, especially if the water had been in the cup for a few hours. That was part of the reason I bought him a Sigg bottle, and I've gone back to handwashing his sippy cups.

So much of this is persistence - my DS went through an amazingly fussy period with his food when he turned 1 and rejected almost everything he'd eaten so far. He is now 20 months and we are only just getting back on track. I don't know what has changed but he is suddenly willing to try new food. I just kept trying and didn't make a fuss if he refused but praised him to the skies when he consented to try something new.
