Babies have a tiny stomach and tend to be happier consuming small amounts of food throughout the day rather than three square meals. You can build snack time into your baby's daily routine so it doesn't conflict with feedings.
A good schedule is two snacks a day, one between breakfast and lunch and the other between lunch and dinner. Some parents also serve a bedtime snack.
Finger foods, which are likely already a part of your baby's diet, make a perfect snack. Your baby is ready to start eating finger foods as soon as he or she can use his or her thumb and fingers to pick up morsels. Introduce new flavors and textures such as small pieces of ripe, peeled fruit, soft cooked vegetables, chicken, tofu, cheese, or well-cooked pasta.
Essentially any food that your baby eats at mealtime (including leftovers) doubles as a great snack. Choose healthy, age-appropriate alternatives to junk food and high-calorie packaged goods.
Even when it's just a snack, feed your baby in a highchair or securely on your lap to prevent choking. When introducing new foods, wait at least three days between each one so you can identify any allergic reactions your baby might have.
