Prenantals VS flintstone vitamins ? what to do?

i took flinstones vitamins during my whole entire pregnancy with my daughter and am doing so for this one as well. if it helps any i had a 100% healthy baby whose only ever been sick once and she is 15 months old :) and we dont keep her frm getting dirty we arent germaphobes or anything lol. so clearly they helped make her into a strong baby good luck an dim sure flinstones are fine
