S.S.
She should have 16oz of whole milk worth of calcium a day. But 8 oz of milk = 3 oz of cheese... or something close to that. It can be found online, google calcium conversion. You'll find what yogurt, cheese, etc you can substitute. There is no reason to warm milk, there is no reason to warm formula really, except that babies usually drink it easier that way. My son liked his cold and his doctor said that was fine, no harm at all. As for juice: ages 1-6 years they should have no more than 6oz of juice a day because it is full of sugar. Yes, even the 'no sugar added'. So make sure you water down the juice, unless she is only getting one 6oz cup a day. (Ages 7-12 should have no more than 12oz a day)
Lastly, take a deep breath. You're doing fine. If she's in the 25th percentile then she's still on the chart and that means she's healthy.
