A nursery I'm working in has 3 rooms. 0-2, 2-3, and 3+. They move the children up rooms a month before their birthday and count them in the ratio of their new room. i.e. A child 2 years and 11 months moves into the older children's room and is counted as needing a ratio of 1:8.
I'm told it's fine but I can't find anything in the EYFS framework that confirms it. Is it wishful thinking from the manager or have I missed something?
