Honey, you are on the right track with ECI, but that is not all you need, and don't try to rule anything in or out until you get her a full evaluation by a developmental pediatricain. Call the nearest children's hopspital in the morning, get an appointment with a Developmental Pediatrician, and take what ever therapy the state (ECI) will give you in the mean time. If you can suppliment that with private speech and OT, do so. ECI is there to prepare your child to be funcitional, and you want much more than that.
I know this is hard, but try not to wonder what it is until you talk to a DP about her evaluation resluts. You make a big point about being premature, and eitherway, the DP is the one who can tell you what is going on here. They will call in every single professional she needs and put it all into one report for you and give you a treatment plan to follow, and you will not have to guess. One thing that they may not be able to do is to tell you why, and that is very hard when they are little. As mine have grown up (my oldest delayed child is now 18) I have learned that why matters less and less because what really matters is getting her what she needs today to be the best she can. Get more therapy rather than less, and given a choice, always get the test, go to the new office, schedule the appointment, do another therapy...never rest or wait and see, if she is going to just outgrow it, she will still out grow it if you get her that therapy too!
One last thought for you, don't beat yourself up for a second, not one second. You did not work with her on waving or pointing because that is something that kids pick up on without instruction. You can start now if you want, but know that you are not to blame. I am saying this to you, and I mean it, don't do it. That will be the hardest thing you ever do in your whole life, but she needs you to put that energy into helping her. Few people will see how hard you work, but she will. Take as good care of yourself as you do of her.

Please know that there is no evidence that vaccines cause any type of delays, tons of ASD research money has been spent on this myth, and you can be very confident in the results that show no connection. I can tell you that what ever the nature of your daughters delay, being protected against preventable illness is still a very good thing for her, and in my experience with my own delayed children, they handle illness less well than children without delays, so make every effort to prevent what you can. Again, don't try to diagnose this yourself, and try not to worry. Finally, take heart in all the stories about children who were just like yours, but are now totally fine, but try to put these aside and don't have that expectation. It can be very damaging to your own emotional journey if you count on that (been there, done that!) MR
