My 3.10 year old DS woke this morning with a temp of 38.7, gave him nurofen about 9am and his temp reduced quickly and he was full of beans as usual. He went to nursery as normal at 1pm and they called me at 3pm to say he wasn't feeling well and had a high temp. Gave him calpol when we got home at 3.30 and his temp is still over 39. He has fallen asleep on sofa and was complaining about being cold before that. Trying not to panic and wondering about next dose of nurofen. Any quick advice?
