Going to Lapland in December. I've found lots of useful information about what to wear once there, but I was wondering (and I apologise if this is a stupid question but I have a 5 year old with sensory issues to clothes so need to be prepared) - what do we wear on the plane?! Should we be in our base layers, with tracksuits on top? And then just put on thick coats at the other end, until we're given thermal snowsuits? And is it normal to be provided with appropriate footwear too, or should we bring our own snow boots? Thanks!
