My 3 yr old has hand foot and mouth

Chelsea • I am super excited to be pregnant with my second child!!!!!
So my three year old has hand foot and mouth. I am giving him only soft cold foods so it doesn't hurt the sores in his mouth. I have also been putting some cream on the sores on his hands and feet. But I was wondering if anyone knows any other thing I can do to provide comfort for his hands and feet???? Some of his blisters are getting very large and painful :(
