OP,, please get him evaluated professionally. Ask your pediatrician for references to pathologists who are experienced with kids this age. You will hear from family and friends (and here online) things like "Oh, just wait, he'll outgrow it," and while he may indeed outgrow it -- NOT all speech issues do get outgrown, and waiting too long to start speech therapy can make the therapy much harder work for the child. Just get him evaluated and see what you do or don't need to do from there.
