Cow’s Milk and Babies: Wait until One Year

Although your baby may have been on a cow’s milk based formula since birth and has tried other dairy products such as yogurt, you should still hold off on giving your baby cow’s milk for the first 12 months of life. Cow’s milk can cause a number of problems, and differs from other dairy based products in its safety for babies.

Cow’s Milk and Baby’s Body

Under one year of age, your baby’s digestive system simply isn’t ready for cow’s milk. The proteins can be difficult to digest and can cause gastrointestinal problems. In large amounts, cow’s milk can damage the lining of baby’s stomach, resulting in internal bleeding. This is only one of the ways in which cow’s milk can lead to low iron levels in baby and serious consequences.

Cow’s milk is also known to block the absorption of iron, which is essential to your baby’s blood. Iron helps to create new red blood cells and also hemoglobin. Low iron results in low levels of red blood cells and a reduced ability for oxygen to be carried throughout the body. This is known as iron deficiency anemia, and it is common in babies who do not get enough iron through baby food diet. Cow’s milk can cause iron deficiency anemia through both blocked iron absorption and also by causing stomach bleeding that leaches more iron from the bloodstream.

As your baby grows past one year, the digestive system will be better able to handle the proteins in milk, but the risk of anemia still exists, so cow’s milk intake should always be regulated.

Why Some Dairy Products are Safe

Not all dairy carries the same risks as cow’s milk. In foods like cheese and yogurt the processing methods that are used in manufacturing break down the protein and the lactose, making them easier to digest. This is why many lactose intolerant people are able to eat these foods and yet can’t drink milk. The same applies to cow’s milk based formulas, however there are still some babies who can’t tolerate even the dairy protein in these formulas and need a different option.

The main difference between milk and other dairy products is that yogurt and cheese are unlikely to be eaten in large amounts, and are even less likely to replace formula or breast milk. During the first year, your baby needs all the nutrients that are provided by these sources. Cow’s milk does not provide everything a baby needs nutritionally. After one year old, babies are able to use cow’s milk as a beverage because they are eating larger amounts of solid baby foods that provide a much better nutritional base. A baby who starts drinking cow’s milk too early may skip formula or breast milk feedings and lose important nutrients.

Until your baby is a year old, the only beverage that is really required is breast milk or formula. Along with meeting all of your baby’s nutritional needs, they also offer plenty of fluid intake to keep baby hydrated. Once your baby is a year old, you can start to replace these feedings with cow’s milk and wean from the breast or bottle. At this time you should still be cautious that baby gets less than 24 ounces of cow’s milk every day. This will prevent anemia and also make certain milk isn’t replacing meals.
