We advocate for educating your daughter about her body and its changes early and often.
While it's important to stay on-top of her changing body, and to know that these changes can help you know how she's progressing along the puberty-process: from body hair, to breast development, to period. It's also important to have small conversations with her about all of these changes. They may start-off uncomfortable but they will lead to a more open relationship with the adults; and those adults in a better position to help her make important decisions.
Research shows that girls are going through puberty at a younger age than ever. They are also discovering that its an ongoing trend with girls in the future likely developing even younger. They call this a "loss of childhood."
This post is only here to share the research and hopefully arm you with enough information to have the first conversation. As you will read, early periods can have negative consequences on a girl's self-esteem and outcome if not well addressed by the adults in her life.
We know that you are the best chance to "normalize" your daughter's puberty experiences. We are here to hold your hand and help.
