With that temperature I think it's more likely a virus. High temp, clingy, runny nose and going off food are all classic toddler with a bug.
Hi Tyika, my son is 14 months and I'm expecting my second too. I'm going through same with him. His temprature is kind of OK but he refuse food even his favourites one and I was thinking its teething phase
Definitely sounds like a combination of maybe a cold and teething...try giving calpol and nurofen (can be given at the same time, calpol every 4hrs and nurofen every 6)
Definitely teething related, some babies even get really bad runny nappies etc when teething. Xx
