My 2 year old can chew gum, no problem. Of couse she saw my older 2 chewing it (ages 6 and 4.5) and had to have some too. I let her try it and low and beyhold she chewed it like a champ without swallowing it! You never know until you try, if they don't do well with it then wait a while before offering again. My little one can chew a whole piece of sugar free gum fine. We don't make a habit out of gum chewing, but when it does come up she does fine.
