If you're concerned about reports that milk and kids don't mix, UC Davis Cooperative Extension nutritionist Sheri Zidenberg-Cherr can clear the air. The key is the child's age. For children under one, breast milk is the best. After the first birthday, whole cow's milk is just fine, says Zidenberg-Cherr. Skim or low-fat milk is not recommended for children under two years old because of the high protein and electrolyte content and low calorie density. She says that children aged two through ten should consume two servings of milk and milk products daily. Older children should have at least three servings daily.
