Welcome!
I am very sorry to say that you will just have to suck it up for the next two years or so, until this will slowly get better. Yes, other kids will start speaking rather well by the time they are two, but only a very few and they will turn out to be gifted, too. Only by three years and up will those very noticeable differences in language output slowly subside. Then of course, your kid may have started reading, but at least it is possible to keep that under the radar. If your kid turns out to be pg, it is highly likely he will continue to stick out in some way for a very long time, and it depends on his social skills and his conflicting needs for integration versus authenticity how well he will blend in at some point.
Have to go and put kids to bed, will be back later with hopefully more hopeful and helpful stuff!
