Okay mommy, pwede naman mag-switch pero since 3 months pa lang ang LO, I'd really suggest checking with your pediatrician muna para sure na okay ang transition, some babies can be sensitive sa formula changes, and you want to make sure S26 Pink has lahat ng nutrients na kailangan niya sa ganitong young age. One of my mum friends switched formulas at naging digestive upset agad ang baby niya, so mas safe talaga mag-consult with the doc first bago mag-commit, especially since yan ang main concern mo ay ang paglalaro lang at pagkakalat, kaya maybe may better approach pa!
