How much notice do you require Nanny Alice?

Ideally a couple of days is fine. A week or two in advance is ideal as you are then likely to get the day and time you would like to visit. Also, I do not have more than one visitor per day visit my bizarre nursery here in London UK.  It is very important to give the best of myself to the select few I see each week. I do not do same day booking EVER.
