It's likely that the website is forcing the use of https which encrypts the data, hence you can't find the password.
You can make your browser generate decryption key info (see the Wiki page on TLS for more info), but as it's likely that the sites your children are using are also using https then you won't be able to decrypt their traffic unless you ask them to configure their browsers to give you the decryption key info.
