My DS is just under 7 months old and has a very severe case of chicken pox. They appeared on mothers day and then my daughter had spots appear too. She's 5 and is coping brilliantly. My DS on the other hand seems to be very uncomftable and is having real problems sleeping and settling generally. I've been told about bicarb of soda baths with tea tree oil in, this helps a little bit, anything else I can do to ease the symptoms??
