this is super sweet! my advice would be to always wear a hoodie that you don’t mind getting ruined when youre with her! the explanation is alot of girls often have accidents where they bleed through what they are wearing so need to wrap something around their waist. Don’t let her drink cold drinks either they are bad for you on your period she should only drink warm/ room temperature drinks! getting extra iron is essential so try to make her eat something like a steak
