A Couple of Tips Use organic fruits and vegetables (either fresh or frozen) if possible. Start with peas, carrots, sweet potato, acorn and butternut squash, blueberries, peaches, apples, pears, and prunes Strawberries, oranges, and tomatoes often cause allergies so wait until your baby is a year old to try these. Avoid strong tasting foods such as broccoli, cauliflower, and onions until you baby is older. Ripe bananas and avocados are not cooked, but are mashed with a fork. Add breast milk or formula to make a creamier consistency.Buy a couple of extra ice cube trays just for your baby’s foods. Do not add salt, sugar or fats such as butter or olive oil to start. These can be incorporated later when your baby is older. Don’t be afraid to mix and match fruits, vegetables, and meat or fish. For example, peaches with chicken and rice cereal.
