Around six months old, baby will start eating solid foods!
Some pediatricians recommend the transition around four months; pay attention to your baby. If he’s still vigorously thrusting a spoon out of his mouth at four months, try again at five or six. I think I tried at four months with my first child, which caused some digestive issues, so we tried again at six months with no problem. Jjust pay attention to your child’s needs! Baby should be able to hold his head erect and upper body stable before he starts solid foods.
Cereal is a good first food. I preferred single-grain oatmeal to rice (rice was constipating for both of my boys). I mixed it with breastmilk. You can use formula or water to get it to a consistency your baby can eat easily. Just a few spoonfuls should be enough to start.
When introducing solids, you only want to introduce a new food every three to four days. This way, you can make sure that if baby has a reaction, you know which food he is reacting to. After cereal, mashed avocado is a good one to try, or pureed sweet potato. Cooked and pureed carrots and other nutrient-rich veggies are good first foods. Then, move on to fruits, and cooked and pureed meats after that.
Don’t get discouraged if baby rejects a food once, twice or several times. This is normal! Keep trying. After you’re sure he is not allergic, mix it with something you know he likes to introduce it again.
