I got it from dd1 while pg with dd2. I freaked out thinking it was chicken pox as I didn't have immunity to it. It was uncomfortable but no harm was done to dd2. Dd2 got it while I was pg with ds, but dd1 and I didn't get it. We changed her bedding and pj's everyday. I washed my hands after each nappy change and used the alcohol gel. They get the blisters internally too so be careful with the poo.
