We are meant to be taking our 4month old DD to spend Christmas with her cousins but one of them has come out with chicken pox today. We were going to cancel as we thought it might be dangerous to expose such a young baby to the virus but my SiL says her doctor told her it would be OK. Apparently he said that babies rarely get the pox and if they do it is usually mild. Is this true? Are there any dangerous complications from chicken pox that might particularly affect such a young baby? Would you change your Christmas plans in my position?
