Ds aged 2, has been up for hours in the night coughing. He seems a bit off colour and tired today and just wants to lie down with Cbeebies on. Everytime I try to switch it off he cries and clings on to my legs. He doesn't want to do anything else and is a bit tired from waking up in the night. I feel guilty having the TV on all day though - but he isn't feeling great. Would I be unreasonable just to let him lie down and watch TV today?
