Uniforms except maybe jumpers or p.e. shorts still in good nick I replace every year (I've already bought September's). School shoes always.
But what about rucksacks, lunchboxes, pencil cases, p.e. bags etc?
Do you replace these regardless of wear and tear? Is it unfair not to when their friends have all new? Is there a social norm? I should really know by now but it still baffles me. There doesn't seem to be any reliable logic to it.
