Its tricky isn't it and I personally think we can have all these plans but its only when we start doing it for real that we will find out if/how it will work in practice. Hand on heart I would have preferred not to go back until Sept, but then will it be any different..I think I have a great one way system and staged drop off "plan"...but until real people (and their children) are using it I have no idea if its going to do its job or not......but then in some ways that's like childcare full stop....we plan, put our hearts and souls into our work, invest our time into making sure we deliver and yet from time to time it still all comes crashing down and we fail.
