rainbow

Hello so my son who is 11 months old has been really poorly. He has been up all night the past 2 nights, really grouchy and hates beinf touched . He has had a nasty cold for 3 days and then developed a few spots which has blistered. He has 4 on his ear a few around his mouth, 2 on his arm , 1 on his knee and loads around his bits😭 I keep getting told different things? Would you say this is the start of chicken pox or not? Can some give me some advice to 🙏🙏🙏
