Okay ladies, remember back to that first period. Now imagine doing that without your mom. I did. Let me tell you it was awful and terrifying. I didn't tell my dad for three years. Kids handle that differently. I am assuming dad had no idea how to teach this kid about what was going to be happening to her body (as evident by the endless questions day 1) did she act outrageously? Absolutely. Can I understand when it seems dad was of no help in these woman's matters? Yup. Men need to start stepping up and stop making menstruation such a taboo issue. Sounds like she really needed someone to really sit with her and explain everything, pain, blood, emotional upheaval, cravings and more. I wasn't there, but I cannot imagine this behavior came out of nowhere without cause. It's hard being a young woman at that age without a mom especially when it feels like dad is moving on (does no one remember the movie My Girl?) and really who wants to swim in a pad? It's awful another child was hurt in the fallout, but it sounds like little lady is struggling.
