My three yr old grandson has been a bit" under the weather"(,tummy bugs and sickness are doing the rounds at nursery) for some weeks. last Tuesday he was very sleepy and had a temp of 40 , Doctor was spoken too and temp controlled by Calpol and wet flannels, temp has remained normal or slightly higher than normal since then. he is still very tired and not wanting to engage, he is drinking but he is not interested in eating, in fact he is not interested in anything.he has a cough but says his throat does not hurt. My daughter will take him to the gp tomorrow, do we need to do anything now
