Well my daughter is only five, but just recently she asked me why she had the day off from school on Martin Luther King Day so I explained who he was and what all he did to gain rights for African Americans. She seemed really curious. Naturally, I didn't tell her about lynch mobs or anything like that because she is only five.
I know that's not directly related to women's suffrage, but I do plan on telling her about it at some point and explaining that as women we weren't always allowed to dress the way we do now, and we certainly weren't allowed to have careers like being a doctor, lawyer, businesswoman, or police officer.
I do think it's important to remind all our children, not just our daughters, that women endured some awful things in order to have the rights we have no. I'm not talking about things like the bra burnings in the 60s, but the protests in the 20s that had several women beaten and thrown in jail without medical attention, food, or water.
Good question, by the way.
