Hi K.,
Aaah, the right of passage into womanhood. I have two girls and like you, have always been very open and honest with them about their menstrual cycles, sex, etc.
Since no two women are alike and needs vary I allowed my girls to pick three different types of feminine protection (liners, thin maxis & teen slender tampons) so they could choose what was best suited for them. After several months they each settled on products they felt comfortable with. And yes, wipes are a wonderful idea; we use them even when not menstruating; the purse packs are great!
Again, each woman is different and so she may or may not experience PMS. One of mine had severe cramps to the point where she would vomit. We had to put her on the pill to alleviate her symptoms as she would miss two to three days of school as a result. Not only did the pill help with the cramping, it regulated her cycle which was all over the calendar and cleared up the acne. My other daughter, to this day, experiences no symptoms.
You and I both know your cycle will often come when it's least expected, your daughter should be carrying protection with her to school in her back pack (Kotex makes a very discreet thin maxi my girls and I like very much). You may also want to provide the school nurse with a note and bottle of Mydol/Pamprin or Tylenol so if need be she can have it available to her should be at school when it starts. Very important note: If she is caught with these in her possession or taking them outside the presence of an administrator she could be expelled or suspended from school; ridiculous I know but it has happened.
Like you my girls father and I are divorced and so I made certain they always had an ample supply of protection at his house. This way she'll be sure to get what she wants and he doesn't have to bee involved which can be embarrassing at this age. I would suggest that you have an off-line conversation with him about it in the event she's with him and gets a little moody. His behavior and body and verbal language during this time of adjustment is very important for her.
I hope this helps!!! Good Luck!
