I came across a great website recently of products for young special needs children -
BeyondPlay. The site specializes in early intervention products for young children, but I have found that there are many products on the site for children of all ages. BeyondPlay allows you to browse all their items via product category or you can search via product feature (i.e. makes sound, etc.)

Some of my favorite products include the Educube (pictured). The single chair with the tray table is the perfect size for toddlers and preschoolers when they are working on skills or therapies at home and it doesn't look anything like therapy or special needs furniture! You can sit on either the chair or the bench on either side - one side is higher than the other, which is great for younger children, and allows them to still use it as they get older (and taller). As you can see, you can use the bench to either sit on or for a table in itself. Of course, these are for children who do not have major tone or stability issues, as there are no belts or cushions to help hold them in place.

They have plenty of toys (regular mainstream ones as well) that are divided into great categories. There are products and toys for sensory exploration and early exporation and even oral motor. For my daughter, the Melissa & Doug jumbo knob wooden puzzles (pictured at left) have been great for fine motor and cognitive skill building. Beyond Play has these puzzles for $10.95 each which is a good price (although you can find them about a dollar cheaper at
Amazon.com for $9.87 each).
One of the other things that many of our special kids gets introduced to is the Wilbarger Brushing Protocol. (You can also read more

on the Wilbarger Brushing Protocol in my other post HERE.) Whether you are familiar with the Wilbarger Protocol or not, the main "tool" used for it are what are more commonly known as surgeon's scrub brushes. Finding the brushes is not simple, however, unless you want to order them from a medical supplier (who usually sells them by the case). Beyond Play has the brushes available, and I think that is great! There are so many therapists and parents using this protocol and now there is an easy way to get extra brushes when you need them.
Finally, the site also has a
"special offers" page of clearance and marked down items. While there are never many things on this page, I have found items here before that were very useful marked 50% off or more. Its definitely worth taking a look.
In all, I think this site is a great starting point for not only buying products you need for your special kid, but also a jumping off point. You can get great ideas on how to use toys and navigate your way through products that deal with the
specific issues your child faces every day.
