Hey so i am soon 16 and my mon told me she used to hit my chest when i was younger bc she said they started growing. Now mind you i have really small boobs and i am a small cup A. Its literally one of my biggest insecurity and i am actually really mad at her now. My older sister has quite a big size and my little sister has her bigger than mine (my mom never hit her on her chest) i feel like its my moms fault tbh 😭😭😭 does anyone know if that may be the reason?
