Trying not to make a big deal of this one but how do I stop him from biting his nails. Is also wetting himself a lot lately, started new school in January and its mostly started fromm there although we have always had to do a lot of remindinig on the wee front. The nail biting is definately a new thing. He is also chewing pencils and stuff at school which is new. Im sure he is anxious about school life in somme way although he doesnt tell me he is and is happy going to school and when he comes out.
