Fruit Juice
Once your baby is eating solid foods, his need for liquid will increase. About 90 percent of all infants consume fruit juice by the time they are 1 year of age. The most common fruit juices are apple juice, grape juice and, more recently, pear juice. Fruit juice has been recommended by pediatricians to provide extra free water for normal infants and young children. However, if a child drinks too much juice, sometimes it can't be digested properly and can result in gas or diarrhea. Some fruit juices, such as white grape juice, may be digested more easily than others because they contain a balance of carbohydrates and no sorbitol, a natural sugar.
To help regulate the amount of juice your child drinks, make sure your child's daily juice intake does not exceed 4 to 6 ounces, offer your child fruit juice with food to slow down the rate at which it's absorbed, and serve a combination of one-half juice and one-half water. If you offer him extra milk, formula or juice at mealtimes, you may curb his appetite for solid foods, so instead try giving him water with his meals.
Cow's milk
By 1 year of age, a child is usually eating table food and drinking cow's milk in place of baby food and formula. Unless your child's pediatrician tells you otherwise, do not give your child cow's milk until after his or her first birthday because it is too concentrated, and may cause allergies in younger children.
