Oh yes. Started at just past two.

She's always been scared of the neighbour's chainsaw or anglegrinder, the drill, and our electric beater in the kitchen. They are loud and scarey, that's fine.
Then it was trains. Yup, trains are loud and scarey (unless you are watching them with mum), that's fine.
Then thunder. Yup, thunderstorms are loud and scarey, that's fine.

Then it was the kitchen tap. Then the kettle. Then the bath running. Then me sneezing. Everyday noises that aren't actually that loud, that she hears every day, and that weren't scarey before.

It got to the point that you just had to reach for the kitchen tap and she'd run out of the room crying and screaming "Scarey!" and slam the door behind her, so we knew she's just being silly.

She's just getting over it now at 2.5. When she comes across something "scarey" she puts her hands over her ears and grins at us.
