I am not sure how a chicken pox party works, but my son was confirmed today. It is mild (maybe 20 right now, just came up yesterday), not crusted yet, and my daughter was fever yesterday (how it starts) and stomach ache today, pretty sure she is about to get it (his twin) and my 4 year old has a couple spots. I have 4 kids, so hoping they all get it! Again, not sure how a party works but I have been hoping for this as my kids are not vaccinated. Not sure where we got it! Please let me know if your interested lol!
