Hi S. - there are responses all across the board in response to your request but I would highly recommend that you consider having your little guy tested for a speech delay. Your son sounds so much like my little guy - happy, very smart, active, interactive, able to perform tasks beyond his age . . . but doesnt have a lot of clear language.
If you live in Colorado, there is a Dept of Education called ChildFind that offers speech, hearing, and cognitive assessments for FREE to help identify kids with delays as early as possible. The links are listed at the bottom of this message. There are other states that offer this program as well. They have programs for kids between birth and 21. They have a program specifically for kids 18m -36mos. You don't have to wait until he is 18mos to call them and set up the appt. for testing.
I had my son tested when he was just shy of 2 but I had been talking to my pediatrician about my concerns since my son was 15months old. I knew about Child Find because my niece is receiving speech therapy from them but I didnt call because I thought I was over-reacting, my doc said he was probably okay, just "behind the curve', etc. etc. I did all the things people said in these messages.
Finally, I knew I just had to take control of the situation and I called Developmental Pathways, part of the Child Find Program. They told me that I could have him tested for free. They reassured me that if he qualified for services, then we were on our way to solving his problem. If he didnt qualify, then I would gain some peace of mind and they could offer some strategies that I could implement on my own.
My son was tested as being 6-8 months behind on his expressive language and 4-6 months behind on language comprehension. They tested his hearing a couple of times as well and determined he had intermittent fluid in his ears. Temp hearing loss is probably what caused his delay. I was amazed because he is a really smart little kid and could do things my first son couldnt do until much later. Our speech therapist comes to my home 4 times a month for an hour to work with my son. His progress has been really fast and fun to watch. My only regret is that I wasted 6months at the beginning. I encourage you not to wait and have him tested. If he's fine - then wonderful! But if he needs help, then there is a program available to help you where he could be receiving 18months of speech therapy help for free.
Please feel free to write to me if you have any questions or feel like you need any encouragement during the process.
Best of all things to you and your little man!!
