Start alternating. If she had milk last she has to choose juice or water next. My son hated that transition but he was drinking so much milk. Keep consistent about it and she will learn. Some times for my son hes more accepting of his option if offered ice in his water or a juice box.

If we do juice I make sure it’s the 100% juice ones. Or the v8 fruit smoothie drinks.

Girl if your kid is drinking nothing but milk and water, you’re doing something right. Juice just rots their teeth & makes them full on sugar instead of actual nutrients. Fruit smoothies are a better idea if you’re trying to get fruit in her. I just mix bananas, strawberries, kale, and for the liquid I do half whole milk, half almond milk. But you can replace some of that with something thinner like coconut water or orange juice to cutdown on milk consumption if you feel it’s too much. My baby boy is a huge milk drinker too lol.

My only give my son his milk when he wakes up and before nap time or like an hour or two before bedtime. And he knows those when he can ask for it.

I personally wouldn’t push juice. Try and push water instead of milk.
