The great thing about Sensory play is that there is no right or wrong way to do it.
The most important part about Sensory play is that the child has FUN!
Children tend to learn more when they are having fun so introduce them to some Sensory play and allow them to Explore, Experiment and Investigate at their own pace.
We as adults are so worried about the children making a mess all over the place that many people are put off doing these activities. We need to train ourselves to sit back relax and watch as our children learn about shapes, colours, textures, temperatures, sounds, and overall self control and the world around them.
When introducing a child to a Sensory activity there is no need to show them what to do, Just present the activity to the child watch what they do and copy what the child does. This could be done by having your own separate tray or bowl of the media so you both have your own play space.
Dry Sensory play is a good way to introduce a child to the world of sensory, messy fun. Dry materials are less daunting to the child than wet materials and are easily cleaned up with a dustpan and brush.
When you think your child is ready to move on to more Wet Sensory play activities it is a good idea to do this gradually, so continue with Dry Sensory play but adapt it, for example start with dry sand and then add a little water to make it a bit more lumpy and sticky or Play with lentils then a tray of water.
But remember to never force a child to join in which such activities allow them to join in at their own pace. Also make sure you check for allergies and skin conditions before introducing any Sensory Play activity to a child
