I'm 13, turning 14 in 4 months. My height is 5"2. All of my friends are a year younger than I am, and the majority of them are taller than me, and earlier in puberty. I have two friends that are 5"4, and one friend that's 5"5 All female). My mother is 5"3 and my father is 5"6-7. It just doesn't make sense to me that many people in my grade are taller than me, but they're younger. I'm told I'm average. Most of my friends haven't started, or just started their period (they tell me everything. Ha ha ) and I started mine a little over a year ago, and I heard that had to do with height. Thanks for reading/answering!
