For the youngest child, how about putting them behind the fun little School Activity Table?  This creative table is perfect for home, school and childcare facilities and can accommodate several children in a variety of seating systems and wheelchairs.  
       
The white vinyl tabletop is super easy to clean and features four cutouts that enable children in wheelchairs to be closer to the table, and to feel more secured.  The red steel legs are height adjustable, also making it simple to accommodate different kinds of chairs.  Young children learn more easily and are less distracted when they can perform their schoolwork on a table designed just for them.

Another innovative choice for young children, or for those who do better sitting on the floor is the Floor Desk that is available in various sizes to ensure the right fit for your own special child.  The extra wide front opening enables easier access for the student, and also for the teacher or therapist to work with the student at the same time.  
        
Height and angle adjustments of the reading and writing surfaces allow for three-dimensional activities and provide maximum comfort for reading.  This beautiful desk is made of real oak and handcrafted to be durable and tough-it can take a lot of abuse and will still last for many years to come.

              

The front and rear surfaces both slide out three inches from their meeting point to allow access to wires and plugs and to maximize user adjustability.  Your child will love the independence of being able to adjust the computer keyboard and monitor surfaces to her own needs and you will love the ideal ergonomic positioning which will enhance your child's physical health, and help her to stay focused on the schoolwork and learning.
