Okay, so a few of us have done this switch din, and honestly it really depends sa baby mo, some kids adjust fine within a week or two, pero may iba na nakakaproblema sa tyan or may constipation pa, kaya you might want to do a gradual transition by mixing the old formula with the new one first para hindi shock ang sistema ng baby. Best talaga na i-mention mo sa pedia mo kung okay lang mag-switch, especially if your little one has any sensitivities, kasi they know your baby's health history better!
