Other forms: indulged, indulging, indulges
To indulge is to let yourself or somebody else have exactly what they want. No resisting, and no rationing.
It takes in when it is yourself, so indulging in a second helping, and a direct object when it is somebody else, so indulging a grandchild. The word carries a hint that this is not entirely wise, which is why it suits treats and spoilt children equally. The noun indulgence covers both the act and, historically, a pardon sold by the medieval church. Self-indulgent is a criticism.
