One of the worst things about chickenpox is that the child is contagious before you can see the spots! So you send your child to school or creche etc and have no idea they have it.
Its a horrible illness for kids – ours were very poorly with it. We kept them inside for the first week and then once the spots had crusted over and they were healing, we got them back out and about.
Poor little mite – hope they have lots of calomine cream in Italy
