If you live in a relationship setting, remember that the quieter times that your other half needs throughout the day still apply at Christmas time and perhaps even moreso. Times without TV and times when they don't want to engage in conversation, are still important to them so try and ensure these are adhered to, even when there are a lot of other things going on.
Remember that it can sometimes be difficult for us to speak up and mention issues so if you can stay aware of potential sensory triggers (which you'll probably already know about anyway), there's a better chance that issues won't arise.
