What the physical therapist said is true. My son did it too. I just rearranged his body into what we used to call "indian style." now called "criss cross applesauce" in school. A physical position can cause physical problems, but not developmental delays in other areas. The language delay is another area entirely, but a part of your child's overall disablity (if he truly has one). Super Duper Publications is a great resource for toys, CDs, computer games, and activities you can use at home to help facilitate language. The website is superduperinc.com. It is for speech therapists, but also for parents.
