How can i develop writing skills in my 3.5 year old as she claims that her hand pains while writing?

A. hi mom, don't worry your kid is too small and don't expect that your kid should write a sentence.. keep this gradual process it will take time to develop writing shoulder of a kid.. first thing is try to improve motor skills give baby safe dough or colourful dough of wheat or maida to play with to kid, you also help baby to create different texture for things with the help of do give rangoli for sand to play with or to draw in rangoli sand or Suji also.. let baby write on wall with the help of chalk or you can put or stick sheet on wall which can be removed after some time.. let me be right on wall which will help to develop writing shoulder
