All kids can be affected by sensory processing issues. Certain situations just make them freak. So it makes sense that exposing kids to a variety of sensory activities in a calm, playful manner can alleviate some of these problems.
In that spirit, we've put together this list of 99 sensory activities for any child. Though these activities involve sensory stimulation, they are great all-around activities for any child, from toddlers on up. Some are even good for babies. These sensory activities also can help you. My kids' school's occupational therapist once gave a seminar to parents on sensory balance and activities for maintaining a sensory-savvy schedule. I now realize my engine tends to run too low and I need to work harder at energizing myself throughout the day. I have incorporated some of these activities to keep my own energy up.
