When my oldest of 3 turned 18, I then had 3 teenage daughters. It was probably the hardest parenting year we ever had. I had always and still say," when they turned 13, the aliens took over. They returned to human form somewhere between 21 and 24. They are now 31, 28, and 26. The 2 oldest are married with 2 kids each and the 3rd is 15 months from her PharmD. degree. We all survived and are great friends. Hang in there and wear out your praying knees.
