jack is a 2 year old boy, he's kind of advanced for his age, he knows how to speak mostly and talk, he's still in diapers and is still mostly a regular 2 year old who depends upon an adult to do things for him, feed him, entertain him, change him, etc. he's kind of bratty and sometimes doesn't like to listen if you tell him to do something he doesn't want to do and he will throw a fit, overall he's just a normal 2 year old
