Hi, our baby girl 3 months old has developed a habit screaming her lungs out or till there is no sound, when we dress her. It always starts when a top goes over head and arms need to go through, or a coat when her arms go through, or baby grow again with her arms. We are so gentle with her getting dressed, but is so distressed with her arms. It only developed a month ago, she never had a problem before. Also, we are sure she isn't in pain as you can move her arms and dance with her arms and she doesn't fuss. Any ideas?? Thanks
