Dear Dr. Meg,

My 4 1/2 year-old-son has started chewing his shirts around the neckline, badly! He now has started chewing on his sheets when he goes to bed at night, then cries and complains he can’t go to bed because it’s too cold. (Which of course because it is so wet from him chewing on it!) I am at my wit’s end! How do I stop this and his behavior, I am also very concerned about. He has always been a very sensitive person. He cannot stand loud noises and covers his ears when he thinks something is too loud (which the noise isn’t even that loud). I know I have been yelling a lot at home lately, with a 4 1/2 year old and 2 1/2 year old who fight constantly. I can’t help myself. I try not to but after hours and hours of this I can’t take it anymore and I don’t know what to do!! Neither boy listens to anything I say and nor do they take me seriously. I don’t know how to turn this around. I’m worried about them and my behavior as well. It’s not good for our house to be in such…
