Only two spots - is it Chicken Pox??

[Wilkiepedia]

Background: DS (2yrs) been in contact with 2 children who have come out in CP over last 4 weeks. He has been crabby, high temp, dry cough for about 10 days and Tues afternoon came out with a big red spot with blister in centre on his tummy. Tis morning there is another big red spot with blister in centre next to it but no more.

Is this likely to be CP? Can I expect more spots or is that it????? I thought they got covered in spots within 24 hours of first one appearing.

Help!

ds2 has had it 4 times,2 of those times he only had a few spots.sounds like cp to me!

Yeap sounds like it my dd1 got them at that age and she had very little spots v dd2 who had more spots than clear skin, its just so variable btn children,
prob will get some more spots
