My son is starting school in September, and I am having to change my childcare arrangements. I also have a 16 month old daughter. I need childcare for 2 days a week and I am thinking that a nanny is probably easiest to avoid an array of different pick up and drop offs. Does anyone have any advice on nanny agencies - there seem to be hundreds covering the area, and are all very expensive too! Or is there some other childcare arrangement that I haven't thought of?
