Around age two, the toddler starts to use personal pronouns. They refer to themselves as “I” or “me” and they refer to anything they possess (or wish to possess) as “mine.” Prior to using personal pronouns, toddlers might refer to themselves as “baby” or by their own name. Alternatively, they would use only verbs and nouns to express their desires (“want juice”), rather than identifying themselves as the source of the desire, as the one who desires.
