Antonio appears as a toddler when his family still lives in Monte Vista. He lives with his parents and sister. At this time, Claudio hasn't been born yet, as Isabella is still pregnant. He's good friends with all members of his close family, though he hasn't met his grandparents yet, Valentine and Silvia. In this town, the Montys haven't met the Capps yet, thus there hasn't been a family feud at the time. Antonio is one of the only toddlers in Monte Vista from The Sims 2 base game; the other one is Goopy GilsCarbo.
