It may help if you mark one of your babywhisperer notification emails as Safe. How you do this will depend on your email program, if it works for you then you should be able to reactivate your spam filter again and still receive notifications from BW.
To clear your cookies and temporary internet files please follow the instructions below. Please note these are instructions for the latest version of Internet Explorer (7). If you are using a different browser, or older version of IE please let me know and I'll post the relevant instructions.
OK, clearing cookies and temp. internet files will delete your browsing history and also any passwords you have set to automatically log you in. So you will need to log into this site again manually.
Make sure you only have one window of Internet Explorer (IE) open. Click Tools, and then Internet Options. Then under Browsing History select Delete. You should have a menu of options, you can delete all if you like, or you can delete one by one and just exclude Passwords (doing this may save you having to enter passwords for all your sites). Deleting Temp. files could take a very long time if you haven't done it recently.
Once all operations are finished it's important to close IE entirely - all open windows. Wait a few seconds and then open again, log back into the site and see if that fixes your problem 
As an aside, deleting cookies and temp. internet files should be done as weekly maintenance
