hi
I would just have parent fill in personal record form (or accept a copy of the one held by current minder), email my policies and get them to sign to say theyy have read understood and agree to them. Then a permissions form for first aid, seeking medical attention, outings, leave with assistant in accordance with ofsted regs, photos etc etc.
I would not off free settling in sessions either, for this amount of time. I would invite Mum for a chat and a coffee with lo to come and see my setting, get familiar with my face, generally just to get to know me enough that I am not new unknown and scary when lo attends for real. So lo knows me as 'the nice lady mummy had a cuppa with' kind of thing....
I would also take full payment in advance, regardless of arrangements with other minder

Good luck
