Anyone have issues on LO having sensory integration issue? My 17mo LO refuse to touch on all kinds of different textures; sand, flour, dough, water bean etc. What can I do to help her overcome this problem?

Usually I would start with the textures that are not so overwhelming. Usually that will be beans, dough and probably flour and sand. I will also grade the exposure of materials usually in a play setting. Ie. Start with using a tool like spoons to scoop to touch the materials and then you can also put a toy that they like into the materials and let them play with the toy. When they are more willing and accepting then you can try getting them to touch it with their friends. I will go slow with the exposure of the materials as you do not want to Create too much anxiety it. Follow the lead of your child. Also if they are tactile defensive you might also want to look at other sensory systems to see if they are also sensitive such as sound ( toilet flushing sound, hair dryer)
