Also...is there something inbuilt in us that would rather fear something than not?
The reason I ask this is because i'm not scared of spiders at all, infact i'm rather fond of them and never kill or harm them if they're in my house, however my eldest daughter is terrified of them and will almost cry in fear if she sees one, which in turn has made my toddler scared of them too.
What i'm getting at (in my roundabout way!) is that despite my reassurances to Mini Boo that spiders are 'nice' she seems to prefer being scared of them like her big sister.
