My son is one year old and today I had noticed that he was shivering and his hands and feet were cold and purple. He has been playing in the garden, the weather wasn t warm like yesterday, it was a little windy, so I thought his got cold inside of him so I immediately put his socks on and wrapped up with the blanket. His been back to normal but I feel his got a mild temperature. I ve given him some Calpol and and fed him just before he s asleep. I just want to know why this happened and how to prevent it from happening again. Thank u you
