infantophiles

Example:It is important to note that 'pedophiles' and 'infantophiles' are not necessarily exact opposites, as pedophilia is about attraction to older children, while infantophiles are specifically about infants.

Definition: Individuals who are sexually attracted to prepubescent children, which is different from being attracted to infants, who are not sexually mature. This term is not a direct antonym for 'infantophiles', but would be relevant in discussions of attraction to very young children as opposed to newborns or infants.
