The gender of the French word "l'enfant" is masculine.
"seul enfant, enfant unique". This is not gender specific, and the words "fils unique / fille unique" (only son / only daughter) are more common in spoken French.
The word "enfant" is both a masculine and a feminine in French, so you can write "un enfant" for a boy (or even a girl) or "une enfant" (for a girl only). The plural "les enfants" could be both feminine and masculine, but it is very likely that the vast majority of French speakers understand it as masculine, the masculine being also the mode you use in French when being "unspecific" about the gender.
