I had a 2 year old who couldnt talk, too. He's now in 2nd grade and quite behind his classmates academically. But socially, he appears very comfortable and many kids seek him out for play.
I am a nurse, too, and I realize today that if I could do it over, I would have them in age-appropriate settings as tots instead of carted around by only me. I think of how many times I told my children, "Oh no! Stop that!" or "what are you doing? No, no no! don't do that!" because they explored my adult-appropriate environment. In the childcare setting, they have LOTS more to do for their ages-n-stages, including other kids, and to me, that seems healthier than what I actually provided. That's in rectrospect. I guess in hindsight, we can do anything better, and today I can see more clearly that my children would have benefitted a great deal from an early childhood program.
Now that I'm past my early childhood parenting, I can see that little kids really seek out AS MUCH STIMULI AS THEY CAN to develop. I wish someone had helped me get into a program like you have.
It might have resulted in less loneliness for me, as well, more opportunities to meet parents of other kids like mine.
I feel for you, I have been there. And today, I am trying (but failing) to make up for the money we lost by my years of not working to stay home with our kids, because (go figure) the grade-schoolers actually need their parents more, not less, than the tots did. Its very challenging to be there emotionally and socially for a grade schooler when we're trying to be out at work, earning money.
I feel for you, I really do. You're in a hard time.
