Ay, don't worry mama, two months of folic acid won't harm your baby, kaya ka talaga nag-worry for nothing! Folic acid is actually water-soluble, so ang excess ay naturally napupunta lang sa urine mo, hindi nag-accumulate sa body like fat-soluble vitamins kaya hindi siya dangerous even sa higher amounts. A few of us moms din nag-start ng folic acid late or had that same worry, pero lahat ng babies namin okay lang, so I'm sure yours will be too! Still, para sa peace of mind mo and para malaman kung ano exactly ang baby needs now at 4+ months, I'd say check with your OB sa next visit para ma-guide mo lang properly moving forward, yan ang ginawa ko kase first time mom anxiety talaga is real, haha!
