Infantophilia or nepiophilia (nepi for short) is the sexual attraction to infants and toddlers, defined by various studies as children aged 0–4[1].

Many paedophiles attracted to females may also experience a nepiophilic attraction, unlike the majority of male-attracted paedophiles who are more likely to experience a degree of ephebophilic attraction.[Citation needed]

The concise Oxford English dictionary twelfth edition (2011) does not contain an entry for infantophilia nor nepiophilia, despite both being scientifically accurate and accepted terms for many years. The website for the Oxford Dictionary does not contain any matches for either word.

Wikipedia categorises infantophilia as a sub-type of paedophilia where the preference is for children below 5 years old.[2]
