This is my little sister.
Everyday she waits for me to come home from work to change her soaked diaper.
I always tell her she should change herself, but she always says "I much prefer being changed by you, big brother! You tape my diapers snug like nobody else and it makes me feel so safe!".
I don't mind though, I like looking after her. I just worry that she'll never grow up, most girls her age are looking for a boyfriend.
