Hello,
I can tell that you really want to help your daughter so she is ready to do as well as possible when she starts kindergarten. You have about 6 months until then, right?
It sounds like you took her for an evaluation at Children's Hospital. Were you provided with a lot of suggestions that you can implement? Can you take your daughter there for some therapy sessions?
You mentioned that you learned from that evaluation that your daughter has difficulty understanding language at her age level. You can help her by making sure she understands what you are saying, every time you talk with her. If she doesn't understand something, try repeating it first. Then, if needed, say it a different way. Add some gestures (point things out) if needed. Once she understands, then say your first statement again as part of your praise. "Good! You ...."
Do you and your daughter use books daily? I heartily recommend "talking a book" which involves describing what is happening in the pictures and pointing out details. You can create your own stories. Take turns. You can do this before, during, or after, or instead of reading the story.
I have written a lot about things parents can do to help their children learn to talk better (and understand and use language better). You can search for my many posts on this site and/or consider purchasing my e-book which is quite comprehensive. I urge you to make the most of your next 6 months!
