FWIW, my 8mth old dd only really gets breastmilk for liquid and whatever is in her food. I don't really offer water all that regularly, and when I do, sometimes she'll drink it and other times she lets it dribble out of her mouth if she's not thirsty. I would just keep offering the water and she'll figure it out. I don't offer juice to my kids either (my ds has had it on occasion but it's not a part of his day to day). BTW, my ds only really got hang of drinking water at 8mths.
