3 weeks ago my niece was with my children and came out in pox the day after) 2 of my kids have had pox but i just can’t remember the start of them … my 3 year old had a spot on his shoulder monday morning didn’t think anything of jt ( not been poorly the last few days ) but was quite rough a week ago…) he came home from childminders and hubby bathed him and he has a fair few red marks on body… my son scratched loads and made them look sore … today still no more by the looks of it have appeared but i’m sure i can see a blister on one ? i’m just not sure if bites or pox … TIa
