Dd just started reception so I’m new to this. Had a message a few days ago reminding parents that girls wearing skirts and dresses must wear shorts underneath (this was never specified in the initial uniform instructions). I will get dd some cycling shorts but haven’t been anywhere yet where I can pick some up cheaply. Teacher ‘reminded’ me again today. Is this a thing in schools? I’m presuming it’s for modesty reasons but they are 4! Is it a big deal? Obviously I’ll do it but if it’s so important I’m not sure why it wasn’t mentioned in the initial welcome pack.
