i always heard 10 days incubation and as they're still infectious til the last spot appears.
another evil mommy here, have been sending dd into playschool each day with the words 'go catch chickenpox'
her best friend mother minds one of the other girls there and she has it since the weekend, so her bf should have it soon and then hopefully dd will catch it..... i so want it over and done with young.
although the amount of hugs and kisses ds gets from these girls he'll probably get it first!
