Thank you for all of your responses.... its nice to know I am not alone in this situation. Not so sure about the nanny/au pair option.... although I ran it past my husband and he agreed as long as 'she' was a gorgeous blond!!.
Seriously though, think I will explore all of these options.....
Any more input greatly appreciated though!
Cheers
