Uy mommy, this is a medical question kaya please check with your pedia first before combining any vitamins or supplements, safety lang natin priority, especially sa babies! A few of us moms always ask our doctor bago magbigay ng anything new sa little ones, kaya best talaga if you get their go-ahead. Your baby's health is so important, and the pedia will know exactly what's right for your 1-year-old. Good luck, mommy!
