Hi my 3year old son (nearly 4) has had cold like symptoms for the last 6 days, cough, runny nose, pale skin with red around eyes high temp of around 39, very little apatite and going to bed about 5 pm sleeping to 7.30 am occasionally wakes to use the toilet, has been taking regular calpol 4 times a day to keep temp down and he is also very teary with everything. What should I do?
