I know a sensory board is no new idea, but I thought I'd share the one that we made for Addilyn a few months ago. I looked at a bunch of pictures on pinterest and just combined a few and really just added whatever we could find at Home Depot. Unfortunately all those little hardware pieces are not super cheap, but it has provided lots of playtime for Addilyn so oh well, right?
We bought a piece of plywood and I painted it. Then Chris drilled in a ton of screws for all of the things we bought. We have two lights, a few locks, a wheel, some circle hooks to hold a carabiner, links and a rope. That pink circle was the case for running tape I had that Addilyn loved screwing the cap on and off. She'll put Cheerios or monkeys in there and put the top on and off. We screwed PVC pipe on there and she can drop stuff through it.
It would entertain for a long time at the beginning, but sadly has lost some of it's interest now. I think I'll put it in our garage for a few weeks and then bring it out again with hopes of her spending time playing with it again!
