Same!
We've changed our rooms from being 'zones' (role play , messy, tables etc (children using just get what they want and take it to the room they want it in). Each room is now like a self-contained 'mini nursery'.
Normally we have 3 groups 'babies' toddlers' 'preschool' - now I've got 6
Nappies/don't walk or talk - group of 3
Nappies/walking and talking - group of 3
Nappies/potty training - group of 4 (need room nearest toilets)
Not nappies but not preschool - group of 6
Preschool - not school this year - group of 8
Going to school - group of 8
The groups will have their own room. They will stay together all day. I've cut our garden into 4 sections so that 4 can be out all the time 2 groups inside. Rooms and toys will be deep cleaned daily (as now) and 'reset' for the next day. Each group will have 1.5 staff ( so that staff can cover breaks). That's the only thing I can't keep the same as the staff shifts don't allow for one person all day. I'm looking at one person all morning and one all afternoon maybe - that's my job for this week!
