I took care of my nephew for a week when he had chicken pox as a toddler because I had more patience than his idiot father.
I just kept him occupied during the day and at night I had a tub full of warm water and Aveno to put him in for a bit when he started fussing in the middle of the night.
My son had chicken pox when he was about 19 months old..
he had 2 little spots ..one on his chest and one well somewhere else... :)
I was prepared for a fussy little chap but he was his usual happy self...
He had to stay home from the day care for a few days..
