Vitamin D drops


At my little ones one month appointment pediatrician recommended we give her Vitamin D drops since she is exclusively breast fed.

With my first-she was formula fed but we tried giving her Di-Vi-Sol vitamin d drops and the very next day she had blood in her poop, we stopped the drops and it never happened again. I researched it after and it seems we weren’t the only ones that had it happen to.

I’m scared to give it to my second little one but know she needs to take them, does anyone have a better brand Vitamin D drops they can recommend?
