It can take awhile to get an appointment to a speechie, so if you are concerned it certainly can't hurt to put his name down now. If you find he doesn't need the appointment, you can always cancel later, or go and just be reassured that everthing is fine. Someone also told me that for parents who are with their kids alot, and quite responsive to their needs (before the child asks for things), speech can take a bit longer because the child doesn't 'need' to talk. It kinda makes sense to me.
