Is sickness normal with chickenpox? DS (4.5) has it very mildly- only about 50 spots, no fever- or not so you'd notice- and only mild itching. First spots came on Sunday, he's been off school (of course!) but hardly poorly (lucky me I know!). Then today at 4.30 he was sick and then sick again and then again. Then went to sleep at bedtime and nothing since. Is this chickenpox getting him (he's been running around) when he's tired or maybe a separate bug?
