Sis, hindi ako makakapag-advise ng vitamin combinations kasi medical decision talaga yan! Please check with your pediatrician or pharmacist muna, sila na ang makakaalam kung safe pagsamahin for your baby based sa age at needs niya, kaya ko lang basagin ang budget ng grocery! They'll make sure walang conflict at na-maximize lang ang benefits. Good thinking na nag-check muna before giving!
