Hi N.......
Obvioulsly you don' t think he needs any therapy, or you would go for it. If you don't think he has a hearing problem and if you are not concerned at all........Then I agree with you :o)
Kids develop their speech at their own confident pace. And, if your son was taught to "sign" for his needs, then speech isn't as important because he already knows how to communicate :o) the speech part will come along.
Just ask him to use his words along with his signs....and his language will naturally develop........but at his own pace.
I think this whole "talking by 2" thing was evaluated BEFORE us moms taught their kids to sign for their needs. What is the rush to make then talk if they can communicate just fine? He's not going to Law School yet :O)
I think all the "fuss" from your Dr's is just "routine"......they have to protect themselves over EVERYTHING nowadays. So, in 5 yrs from now, you don't go back and say, "well our dr never told us to have his speech evaluated..." So, they are just protecting themselves. But you are the mom, you would know if your son needs help with this situation.
You have plenty of time to teach him "his words" to go with his signs........just remember.........once he starts to speak............he'll never stop! :O)
I hope this helps ease your mind :O)

you have plenty time to teach him speech.
