Infants with Down syndrome may have slow development in moving, thinking, and talking. This study looks at how early movement, like crawling or using hands, helps babies with Down syndrome in these areas. We will study 45 babies, splitting them into three groups. One group will practice walking on a treadmill at home, starting at around 10 months old. Another group will practice both walking and using "sticky mittens" to grasp things, also starting at 10 months. The control group, starting at 20 months, will not do these activities. We want to see if moving helps them learn and talk better.
- Study lasts until babies start walking and then checks progress five months later.
- Babies need to be 7-24 months old and have Down syndrome.
- Babies with severe medical problems like seizures cannot join.
