A baby’s tummy can be very sensitive to changes in their environment and diet. A reaction may indicate that your baby is not tolerating the sudden changes in his/her diet well. When introducing a change in feeding, you can help your baby adapt by doing so gradually. If your baby is already on a formula, alternating between the old and new formulas may help with this transition. This will give your baby’s digestive system time to process and gradually get used to the new formulation. Similar to the way you would introduce solid foods, i.e. in small quantities over a period of time, we would recommend doing the same with the formula.
While it’s quite common for a baby to react to any change in diet, there are a number of other reasons a baby may display reactions. Not all are necessarily related to feeding. This is why we advise parents that it is important to see a healthcare professional to discuss any unusual reactions they see in their baby.
