My kids are mainly water drinkers. We cut milk out for DD2 about a year ago and it's filtered through the house. Although I'll still have it when I buy my coffee.
But I agree with others, dairy isn't the best so I try and limit it in our house! I was really worried when we originally cut out milk for DD2 about calcium, but was surprised at how little dairy a child actually needs per day and how easily that can be replaced with other things to get their recommended daily intake.
But back on topic, DD1 gets lemonade for special occasions, like birthdays and movie trips.
We don't really do juice, I'm not a fan of sugar so it's just easier to not have juice in the house, because they'd want it with every meal
