It is possible that your baby is experiencing digestion issues with the current formula. Before considering changing the formula, you could try using a product to help ease intestinal discomfort. At this age, homeopathic products like Cocyntal, commonly used for infant colic, may be helpful. If the problem persists or worsens over time, then it may be necessary to switch to a different formula. Remember that it can be challenging to make the right decision regarding feeding during this stage of development. If you have any other questions, feel free to ask.
