Our 3 year old has started coughing since last night, is very hot, and coughs so much he can hardly catch his breath. He is wheezing and his chest is sucking in and out with every breath. He is eating drinking and sleeping. Wanted to stay in bed till 11am which is unheard of. But can still chat away and is eating his lunch as we speak. Is this just going to be a virus and he needs to ride it out or should I call 111? Very red cheeks and temperature too. Thanks
