Sometimes we do a sensory activity with Bentobaby without realizing it. When we took Bentobaby to the park, hubby had her throwing rocks in the water. She thought this was awesome. (even managed to get a few in!) I thought about it later and throwing rocks is very sensory. There is the feel of the stones, (smooth, rough, bumpy etc) the splash of the water from the throw. Bentobaby did great. She did not like the wave that came from the rock landing in the water. That kind of frightened her. Being encouraged to throw things was very enjoyable to bentobaby.
