Paedology

the study of the exclusive sexual interest in prepubescent children (generally age 13 years or younger, though onset of puberty may vary). The child must be at least five years younger in the case of adolescent pedophiles aged 16 or older.

that little boy says that he wants to study Paedology when he's older, I just think he's a paedophile at heart.
