Yep - nanny for some poor health care worker who is on evenings / nights, because normal childcare is not an option. You may even be able to do it at your home or take the little man with you and have him collected later if necessary. It may be even a sleep over option. You could find your local hospital and place an ad there. Particularly with your background!!

It is what I am having to do so I can go back to work. My nanny will start at 11am - 9.30pm and as my hours increase over time she will work until 11.30pm and then 1am when I am back on 12 hour shifts.
