MY dd who is 2 years old has reay bad chicken pox. Last night she couldn't sleep at all because of the itching, so my partner and I took it in turns to stay up with her. Today she's in a foul mood and is literay writhing on the sofa. I've tried calamine, but doesn't seem to help much. Have been told to try Piriton and an oatmeal bath. Any other tips anyone?
