Girls, help ?. I don't know what it is, but I get irritated when my son touches me. Is it because of pregnancy or something else? It's driving me crazy. I can't even drink tea or anything else. I feel sorry for him, of course. But I can't handle this. I clean his hands, he cries. How do I deal with this? Maybe I need to take some pills, any kind? Does anyone else have this problem?
