My 5 year old ds is a constant nose picker. Unfortunately his nose does run a lot and I'm sure that it is itchy. We have recently moved to a new area and he has started a new school. He is finding it difficult to make friends and this can't be helping. He did used to wipe his nose on his sleeves as well and used to come home with great trails up his arms but, fortunately, because he is so proud of his new uniform and he wants to keep it clean, putting a tissue in his pocket every day has cured him of this.
Any ideas?
