Not sure if any of you have had this too, but was really curious as to what it was about.

Its a little bit funny but still weird. DD has never been one to get freaked by loud noises. She doesn't flinch during storms, doesn't easily scare through loud bikes etc. I swear sometimes she could sleep through a nuclear war! But she is terrified by the toilet flushing! Im not even joking! She is NEVER a sooky baby I had soooooo many people comment that on Australia day when we were at a friends house she was such a social baby to people who had never even met her before, she would sit on their laps and play and laugh with them. But everytime she is having a crawl around and I go to the toilet, the minute I flush it she crawls a million miles an hour in the other direction screaming and crying! Now I don't know about anyone else, but the toilet is really the LAST thing that I want her to be scared of kwim? Anyone been through this, or have any advice for how I could fix this? Thanks
