I'm still blown away by the fact that Elizabeth is 6 weeks old and is holding her head up fairly well, cooing and smiling. Her rapid development is pretty amazing to us (Bill and I) and the more amazing thing is that it makes us feel so much more appreciative and prouder of Matthew than we were of him before Elizabeth came on the scene. We see just how much more he has to work to learn and achieve developmental goals. Most things are a real challenge for Matthew - things that would come so easily, almost effortlessly, for the 'typical' child. One day, Elizabeth started cooing and smiling. Another day, she started holding her head up. Another day, she started turning her head 180 degrees. We think she'll start rolling over on her own before we know it. No teaching. No work. No therapy. Everything seems to "just happen". She generally has it easy.
In a way, it also helps us appreciate other families who do not have kids with Down syndrome. Unless a family has raised or is raising a child with Down syndrome, that family may never truly understand how much work is involved, how much teaching has to be done, and how emotional the journey can be. But there's nothing wrong with not knowing, not understanding. Bill and I would probably not understand either if we didn't have Matthew.
