My son aged 13, has major sensory issues and can't bear for me to do the lateral flow test on him. Up till now he's only done a handful as it's too distressing for him but he has started very unwillingly allowing me to do the odd one now on him. He refuses to do it himself but we've heard he may need to do it at school. Are there any tips that might make it easier for him. He even hates blowing his nose so it's a huge challenge.
