Seeing a number of threads where school KW attendances are high - presumably these are in England which are in school this week and so they know. Up to 70% in some schools? It seems English provision is for one KW only to qualify, and doesn't need to be working away from hone.
Our council have a strict criteria of both parents to be KW and both working away from home.
Last time I think it was tiny numbers who accessed KW places, I can't imagine many fit the criteria where we are now, it seems even stricter.
