I have custody of my 14 year old niece, and we sat down a couple of years ago and had a nice chat about becoming a woman and what to expect. She had a class in school on it and came home with questions, so I knew it was time to tell her. Plus she was worried because several of her friends had already started.
It actually made us closer because we had time with just the two of us and we kind of laughed about the different stories I could tell her about when I was in school and that started happening.
Because she was worried about starting and not being prepared, I had her always carry a pad with her in her purse or backpack. And you know what? It sure came in handy when she started at school. And she knew exactly what to do so she wasn't embarrassed or concerned. She just came home and later I saw a wrapper in the waste basket and asked if she started.
She told me she had, when it happened and how she just asked the teacher for a bathroom pass, and she handled it! The power of open communication with your kids strikes again!
