Instead of thinking of snacks as junk food, see them as an opportunity to include a wide variety of vegetables, fruits, whole grains, dairy, lean meat, poultry, and seafood that your infant requires.
Try to offer snacks that can be eaten rather than sipped (unless your child is unwell and unable to eat regularly), because liquids are generally low in nutrients and fiber and can be high in sugar and additives.
Here are some snack ideas: Fruits, fresh fruit juice, smoothies, curd, boiled eggs or vegetable omelet, ragi malt, upma, or any homemade mixture (chivda, murmura bhel).
