Bread and flour are fairly normal in my supermarket (countryside but close to a big city).
DD is in GS and there are 3 of them in her group! It’s only GS in the maternelle at the moment, but I’m guessing around half of the year group are going.
DS is in Ce2 and there are 5 in his class going to school - just under half the year group in his class (combined with CM1 who are attending different mornings).
Both of mine are going to school twice a week for 2 hours each time. Both are very happy to go to school at the moment. However, only 2 hours and no canteen isn’t exactly a tough day at school.
