I think he's ok. My son started talking fluently at 2.

I took him to China to visit and my brother's daughter who was six months younger than he could talk a lot better than he was. Then after one month he started talking more and more. Today he is a chatter box and very smart. Boys are late in language development and also bilingual children talk later since their brain has to process two different languages. However, I would ask your pediatrician's opinion too just to make sure. Best.
