Hi, my dd is almost 6 months now and has suddenly decided that she is now terrified of the hair dryer, I’ve always had her in the room with me when I dry my hair ever since she became active so probably from about 3 months. She cries hysterically when I turn it on. She’s fine with hand dryers in toilets and other loud noises. I’ve let her touch and explore the hair dryer, but she still cries when it’s on, what’s happened? What do I do?
