You can't go wrong with plain water. It hydrates, helps regulate body temperature, and helps prevent constipation and urinary tract infections – all without adding calories or sugar to the diet. It can also be a good source of fluoride, which is important for healthy teeth. If your child won't drink much, get tips on how to get your child to drink water
Flavored or enhanced water
Flavored water may contain ingredients that your child doesn't need (sugar, artificial sweeteners) or already gets enough of (vitamins). It may even contain additives that could be harmful (caffeine, herbs). And it's expensive. You can easily make your own by adding a little fruit juice to plain water. If you're buying one, choose a brand that's flavored with 100 percent fruit juice and doesn't have any added sugar.
Cow's milk is an excellent source of calcium and vitamin D as well as protein and other nutrients that are important for healthy growth. According to the American Academy of Pediatrics (AAP), most kids will get enough calcium and vitamin D if they drink 16 to 20 ounces of cow's milk a day. Offer 1-year-olds whole milk (unless they're at high risk for obesity). Low-fat milk is fine for children 2 and older. Don't offer more than 3 cups of milk each day or your child may not have room for the other foods he needs.
Lactose-free or reduced-lactose milk
These types of milk are for children who are lactose intolerant. They contain the same nutrients found in regular cow's milk, but they tend to taste slightly sweeter.
