Hi there. I am worried about my cousin. He was always really good, happy and funny, but suddenly he became really quiet and nobody knows what to do about this whole situation. I was talking to some of my friends and they told me that there is a possibility that he has problems with separation anxiety. I would like to tell that I know something about it, but I don't. Actually, I don't even recognize what this is all about. So, I was wondering can you help me? Can you tell me how can you recognize separation anxiety disorder in infants? Tnx a lot!
