Hi mama! Congrats on your first baby! Usually doctors recommend starting vitamins around 1 month old, pero definitely check with your pediatrician first kasi depende sa baby, kung exclusively breastfed, formula fed, or mixed, may different recommendations. A few of us mums sa circle namin swear by Vitamin D at iron supplements talaga, pero honestly the safest bet is to let your doc guide you on what's best para sa baby ninyo based sa feeding method at health check-ups!
