Remember, he is your child! Don't worry, kids progress at different stages. As long as he's saying some words you know he can speak that's great. Keep doing what you're doing. Point out lots of things to him, when you're outside playing, show him everything, trees, plants, grass, sky, sun, bugs, houses, cars etc. He will start talking tons and won't stop he'll want to tell you everything! My little boy is two and a half and that's what we did, we always read books and went on walks to find "new" things. He's been talking really well for about a year now. Don't worry, listen to your pediatrician they'll tell you when and if to worry. Just enjoy your kiddos!
