Question: how much formula and cereal for a 4 month old?
Answer: Baby cereal basics. Mix 1 tablespoon of a single-grain, iron-fortified baby cereal with 4 tablespoons (60 milliliters) of breast milk or formula. Don't serve it from a bottle. Instead, help your baby sit upright and offer the cereal with a small spoon once or twice a day after a bottle- or breast-feeding.
